One thing that would be interesting (just as a thought experiment) would be for Satoshi to make a move that basically says, "Don't. Mess. With Bitcoin." Something that would REALLY get attention. I suppose it's too much to assume that Satoshi still has access to his/her/their original private keys?

If Satoshi Nakamoto's identity is ever to be revealed, it would be a good thing if he/she/they were to control the circumstances in which it is revealed, in any case. That way Satoshi Nakamoto at least has some control over what happens.
