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.
It's obvious that a one world currency is what comes next, the dollar at some point is going to fall, that is inevitable, especially because the US government is treating it as if it is their right to print as many dollars as they want and the world is simply going to take the dollar at face value, so when an economic crisis hit us because the dollar is going through a period of hyperinflation people are going to get desperate and they're going to be willing to accept any solution that is proposed to end the chaos and that is when a one world currency is going to be proposed.
And I have no doubts that the proposal is going to be accepted and even celebrated by the people, however while I have no doubts that governments at that point will try all kind of measures against bitcoin at the same time a lot of people will realize that giving more power to those that created the problem in the first place is not the answer and we will begin to see an unprecedented support for bitcoin.
