I don't think the authorities are allowing it. I've seen news of countries trying to ban and they still are. The ones who aren't are looking at controlling the environment via CBDC (Central banks digital currencies), which taskmaster4450 recently posted about. You can check it out here @taskmaster4450/cbdcs-will-not-help-inequality.

If they manage to implement CBDCs it gives them ultimate authority and control, so it would make more sense to go that route.
