Logically the reasons behind hes unwillingness to disclose whether or not he controls the key to the genesis block make no sense too me.
Lets look at these rationally.
What are your thoughts jb? [reordered]
Most of your list seem to speak to soft considerations such as motivation and social aspects. Not sure these are amenable to objective analysis. But I'll play along.
Pros
1) Revealing control of the genesis key basically tells the world it was never about money.
I'm not sure how this follows. (If it were...) CSW does not seem very shy about flaunting at least some of his money. Enough so that the echo chambers collectively deride his pulling out of the high-end watches, or his Lambo or whatever.
Coins could and should have been dumped many times over if it had been.
I don't get how this follows either. To accept such would seem to obviate the position of hodlers. Which many here probably ascribe to. If one is 'all about the money', and one was reasonably sure that the price next week/month/year/decade will be higher, would one not refrain from dumping? I mean... I hodl, and despite my lofty view of myself and my motivations, I need to admit that it is at least in part about self-enrichment.
2) Even controlling such a big stake of coins that there was a true belief in decentralization. A hands off approach or at least a behind the scenes one over the project direction has been encouraged.
Yes. And if satoshi would reveal his/her/themself, I think it would be natural for their opinions -- technical and social -- to be given weightier consideration by the community,.
3) The incredible social network effect that would happen to Bitcoin knowing that the creator was still around and interested in development.
Hmm. I've always assumed that satoshi's disappearance was a net positive for Bitcoin. But there are so many ways to look at this single event that any possible list of considerations would be incomplete.
4) Banishing doubt over dishonesty or fraudulent claims.
This would seem a solid Pro.
5) ?
Cons
1) Opsec becomes increasingly difficult.
Opsec would become nil.
2) The continuation or creation of a cult of personality.
Oddly, I think CSW already 'benefits' from this to some degree.
3) Becoming(more of) a known fraud and liar.
4) ?
For a temporary lie, dispelled by ultimate honesty? Perhaps.
I've already answered HairyMaclairy. Somewhat obliquely, but honestly. Sorry I don't have a better answer.
