the government can employ great people, hackers, computer geniuses, etc. to help the government regulate cryptos, or maybe the government has done it, just waiting to implement it officially, never underestimate the government.
I find that the importance of bitcoin to the government is enormous; it is possible that they have also invested a huge capital into bitcoin just to know that bitcoin is not scam, this way it is possible. And in the ways listed by you, I think they have seen bitcoin as a real scam.
