I said it before and i will say it again. he is not satoshi he is truing to force satoshi out.
Do you think it'll work?
No.
no way
This is an interesting theory. My own 2 satoshis is that if something like this happened, the real Satoshi would hold his fire until he saw that the bitcoin community was reaching a mistaken consensus and had accepted a con artist in his place. Only then might he act. And even then Satoshi would do so in a way that would protect his own anonymity while demonstrating that false claimant was a scammer. Satoshi doesn't need to hold a press conference or appear in person to demonstrate his identity/ownership of private keys, and use those keys to send authentifiable messages denouncing the scammer.
Yeah, I think his concern would be preventing an impostor from using Satoshi's influence to control Bitcoin, rather than simply letting people know that the real Satoshi is still unknown. That lends to your theory that he would only act if the community reached that mistaken consensus about his identity.
