What can do Governements against Satoshi ?
Nothing, you are right here, but not because he predicted but because he died.
US goverment know exactly who satoshi is. Monitoring all internet traffic and emails, it was easy peasy. They know, but why they don't reveal it? Because it won't do them any good. It was solid person, without compromising facts in his life. That is truth i believe if my facts are correct.
