There are some major flaws in your argument:
1) You are imputing phobias and psychological diagnoses without any evidence or expertise to make such pronouncements.
If you are taking things literally, that is your problem. 'Sethiphobia' is a just a convenient term for the obsession Imran has with everything related to Sethi. If you don't see that, then again, it is your problem.
2) The integrity of cricket was indeed compromised by messing with the composition of a team right at the final. Dean Jones's presence does not change that.
Please explain what you mean by 'integrity'. Sure, the quality was compromised to an extent because of the absence of Quetta's foreign players, but the positives of hosting the final in Lahore outweighs the negative. My thread is not intended to disparage the decision to host the final in Lahore, it is simply a reflection on the fact that the PCB did not make the necessary arrangements from a cricketing point of view. The poor quality of the pitch, the barren outfield, the low lights, the botched national anthem and the disorderly presentation ceremony had nothing to do with the absence of Quetta's foreign players. PCB had more than enough to time to prepare for the final and they failed to produce a good quality product.
However, a lot of good will come out of hosting the final in Lahore. The poor quality of cricket has left a temporary impression, but the fact that we were able to host a high-profile match without any hiccups is an incremental step towards bringing international cricket back to Pakistan. Players like Sammy, Samuels, Jordan, Malan etc. and commentators/mentors like Dean Jones, Viv Richards etc. will be more willing to return in the future. If you don't see these benefits then again, it is your problem.
3) ODI and test record are the yardsticks of a board's quality and success, not staging a T-20 league. Glamour and entertainment are not cricketing qualities. On that count this board recently has fared horribly.
Who said that the PCB is successful because they hosted the PSL final? The PCB remains an incompetent and poorly organized board, directly responsible for Pakistan's lack of success. However, even a broken clock is right twice a day. The PCB has made good strides towards bringing international cricket in Pakistan over the last couple of years, and most of it has been at the behest of Sethi. We hosted Zimbabwe in 2015, there have been continuous talks with WI, SL and Bangladesh, Giles Clark also visited recently and now the PSL final. Things are moving in the right direction and that is all we can ask for at this time. We have to take incremental steps towards bringing international cricket in Pakistan. No one is showering praises on the PCB for doing wonders for Pakistan cricket and none is hiding their incompetence. You are simply creating a false narrative to drive home your point.
4) IK's larger point that hosting a match under piles of state weaponry does nothing to bring international cricket back is still valid. Privileging entertainment and T-20 leagues over international cricket is more dangerous in the long-run. Imitation of corporate India and following popular trends is not equivalent to bettering quality of cricket.
Imran is good at criticism but generally doesn't have a viable solution, and is quite good at stating the obvious. The security problems are a reality, and if we wait for the day where we will be able to host international cricket without any heavy security, then we can forget about it for years and years. If Imran was the PM and Pakistan would have hosted the final, he would not have any problem with the state-level security. Unfortunately he doesn't really have a larger point; he only has an axe to grind against Sethi and has failed to put national interest above his political interest.
His major problem with hosting the PSL final in Lahore was that it will make Sethi look good and PML-N would be use it as a selling point in their next election campaign. As former cricketing legend, he should have welcomed this idea and supported it because the people in Pakistan want to cricket at home and it brought joy to thousands of people in the country. Imran failed to talk all of that into consideration. You are obviously a PTI supporter so it is useless arguing with you on this matter, because you would be praising him even if he would have supported the decision to host the final in Lahore, because that would have shown how selfless he is and how he gave paramount importance to the interest of the people etc.
5) PSL has benefits certainly (exposure to foreign players etc.) but it really is being blown way out of proportion.
Again, you are creating a false narrative to manufacture argument which does not exist in the first place. Who has blown the PSL out of proportion?
Is it good for Pakistan cricket in general? Yes
Is it good for the young players? Yes
Will it help in bringing international cricket back to Pakistan? it should, with the right strategy. PSL final this year, maybe play-offs next year and in a few years, bring the whole tournament home.
Will it make Pakistan a cricketing superpower? No
Does Pakistan cricket have bigger issues that the PSL cannot solve? Yes
That's all. There is nothing more to PSL, and I do not see how it is being blown out of proportion.
6) I respect a leader who makes conceptually sound arguments even if unpopular. The whole "terrorism" was defeated by hosting a cricket match under the arm of a police state is ridiculous nationalistic parading that lacks much nuance.
This whole terrorism has been defeated etc. etc. is definitely nothing more than a PML-N hyperbole, who are using this to their political advantage. However, people aren't gullible enough to believe in it and it has been sold to us many times already. Terrorism will not be defeated unless we could go without any bomb blasts and other acts of terrorism for at least a few years. Only last month, we had a wave of terror attacks, so what defeat? However, because of this terrorism, we cannot just sit and do nothing. That is surrendering to terrorism, and just because we have not been able to defeat it yet, it does not meant that we should surrender to it altogether.
It is not a coincidence that Lahore was targeted right before the PSL final. It was a clear tactic to sabotage the final, and the fact that we went forward and hosted the final successfully without any problem showed our capability to bring happiness for the people of Pakistan and host an event in spite of the terrorism. The spirit of the nation has been uplifted once again and Lahore lit up after the darkness of the terrorism last month.
Pakistani people have been starved and isolated for a long time now, and the government and the PCB managed to achieve something that a lot of us thought was too risky, so instead of political point-scoring, we should appreciate what they did. Regardless of the way PML-N politicized it, the fact is that it brought joy to our people and that is all that matters. However, don't worry too much. The people haven't forgotten that we are still rampant with terrorists and we still have a lot of problems, it was just 24 hours of joy and we will back to our normal lives soon.
7) No he is not petty. That's a polemical statement with no argumentative apparatus or weight.
Imran has done a lot for Pakistan both as a cricketer and a philanthropist, for which he will forever remain a national hero. However, as a politician, he is too impulsive and immature, who fails to look at the bigger picture quite often. His intentions are mostly sincere, but he does not have enough control on his mouth and every now and then, he shoots from the hip and his supporters have to clear up the mess and implore people not to take his comments out of context. His comments in the lead up to the final were extremely poor and it is encouraging to see that a lot of PTI supporters on social media have openly stated that his negativity was uncalled for. Even a respected PTI supporter here [MENTION=21699]Pakpak[/MENTION] stated that he thought Imran's comments were out of order.
