I'm pretty sure by now somebody has seriously claimed that Bitcoin cures cancer, speaks Romanian and cure male pattern baldness.
Anonymity and protection from the Big Bad Government were definitely talking points used by many cryptocurrency enthusiasts. "It can't be banned and can't be seized", rings a bell? Except of course if the Big Bad Government comes knocking at your door and tells you to hand your wallet over "or else".
This part is sort of true. A government can ban fiat <-> BTC conversion but there isn't really a way to stop people from providing services in exchange for BTC.
And how are they going to know you even HAVE a wallet? There are anonymization techniques like wasabi and monero that are fairly trivial to use. It's basically like trying to outlaw software piracy, it's a hard sell.
