The US government tries to control and/or kill anything they can't control. They killed NORFED (National Organization for the Repeal of the Federal Reserve) and its Liberty Dollar that was trying to return a solid gold and silver backed currency to the people of the US instead of the US Dollar which is literally just a paper note backed by empty promises. And indeed, OP hit the nail on the head mentioning the US's large military. I am from the US and I sadly recognize that we are viewed as the bully of the world that tries to stick our nose into everybody else's business.

I strongly feel that the globalists are going to try to switch from individual government Fiat money to a one world digital currency, and since they can't seemingly control Bitcoin enough to use it for that purpose I think they will eventually do everything they can to kill Bitcoin by regulations, taxes, and legal crackdowns. But for now Bitcoin is helping their cause by spreading the knowledge and widespread acceptance of a digital currency.
