Y'know, I completely understand your want to get the information out, to solve the puzzle, to unlock the mystery of
why this guy thinks whatever it is he thinks. I don't have a moral, ethical, or any other kind of problem with that, nor do I think that any reasonable court would hold you accountable for anything of the sort (that said, courts are seldom reasonable, so beware)... what I
do worry about though, is the idea that by even vaguely admitting anything even remotely of the sort that you
might be Satoshi could get you implicated in something else.
This line, for example
> I think that you do not have a solid case that I am Satoshi, and that you are hoping I will pay you a large sum
I read it how you meant to say it, but thinking through every episode of Law & Order, Matlock, et al that I can remember, the guy who says "Oh yeah? Prove it. You got nothing on me copper" is always the guilty party. In the absence of anybody knowing who the real Satoshi Nakamoto is, let's say the feds decide to arrest somebody, and this happens into their field of view, so they settle on you, and you find yourself in front of a jury of your peers with a document that, if read the right way by the prosecutor, makes you sound like Bugsy Malone.
I'm sure it's a remote possibility, and I'm sure that there are plenty of other happenings in your life to provide you ample alibi -- or at least, I hope there are. As a telecommuter that lives in the suburbs, I probably get out less than I should... I don't know how well that represents you, but I can imagine a scenario in which my alibi is the ever-faithful "I was at home. Yeah, my wife was there the whole time".
I'm sure things'll be fine, but be careful. Innocent people do go to prison all the time, especially in America. We damn near pride ourselves on that fact.
