I think it comes down to the motivations, in many African countries USD is not legal tender, but people are still trading it, be it physical or digital because they're local currency is hot garbage. Sure governments can come out and state bitcoin is illegal or limit it for purchases etc but this is assuming they can enforce it, informal economies will always pop up to supply the demand because when a man has to eat what his government says doesn't matter

it's only when governments are not failing the man on the street that there is an incentive to listen.Maybe those in the West see it like you do, but round my parts civil disobedience is baked into the pie

I think the more your currency gets clobbered the more legalities hold less weight
