There's lot here, but I'll make it short:

- The fed does not exercise control over Bitcoin directly, so Bitcoin is still fundamentally different than fiat currencies

- All fiat onramps into crypto are controlled by governments, which is one way to regulate it (KYC, AML)

- You still have to follow the rules for your country, and if the government finds out you haven't, it can censure you; with crypto, it can be harder to see if someone followed the rules, but it's not impossible with the pseudonymous approaches used by most cryptocurrencies today
