It will be reall a historical part in crypto industry if Satoshi back again in forum. But I hope one day the mistry of Satoshi will be revealed and Crypto will be the most popular currency in the world.
hi account is literally locked, he can't come back.
worse case scenario is that CSW is part of satoshi, that would cast him as a crazy/weirdo but seems that literally lost the private keys so he doesnt matter anymore /can't ever prove he is.
he's better as a myth.
