Honestly I don't believe in this whole "government hates bitcoin" thing. People say that without any evidence whatsoever. Nobody in government has ever demonstrated hostility to bitcoin, in fact the new regulations seem to imply they are perfectly fine with it as long as you don't launder money and you remember to pay your capital gains.
They really don't have any reason to want to kill bitcoin. They make the same amount in taxes either way, since you have to pay capital gains, and you have to pay them in your country's currency.
They could actually generate quite a bit more revenue, in fact, if they jumped into the bitcoin market themselves.
Also keep in mind that a lot of VC's in Silicon Valley are jumping head first into bitcoin-related companies, which they would absolutely not do if there was any question about the legality or any possibility the government is about to kill it. VC's get a lot of legal advice before investing in ideas.
IMO the U.S. government has plenty to lose from widescale adoption of bitcoin. People buying gold and other tangibles directly with BTC aren't paying tax on their gains. More importantly in the coming years it is inevitable that the dollar will continue to lose value. The national debt is what, $15+ trillion? Trillion+ dollar deficits have become the norm. There is another tens of trillions in unfunded or underfunded liabilities. The Fed is stuck between a rock and a hard place, with interest rates way artificially low but not being able to raise them without crashing the economy. The only way out for them is to print money and that makes cryptos a problem for them.
