Yeah, the only problem is that others cannot sign messages using Satoshi signature
Also, what makes you think/believe that it is not the church that has been bullshitting you all this time and the real Jesus will come but you wont believe it because that is what you have been told?
Do you really believe in the church?
i will wait for satoshi to come back and big giveaway of these coins that are still in his wallet and this giveaway will be greatest event in the bitcoin history. 
this would only be a great way to kill bitcoin, the majority of the new owners of those coins, will dump it as soon as they hit their wallet
Or, he could just donate to charity or use it for a good cause, like end world hunger
It would be cool if he did return, maby he can come back in a few years time and buy a "small" island in some nice climate zone and make it a no fiat, bitcoin only "country" or something like that.
Yeah, and then the U.S. will send a drone and bomb the fuck out of it....
