Not everywhere, and likely not in America. In Europe it’s not as unthinkable. Climate regulations are having real impact on people’s lives, and yet there is support for them. Spun by the right politician as a ‘free’ savings of XX megatons of carbon, outlawing PoW would be an easy sell. And with a massive bloc like Europe not participating in a certain crypto will definitely reduce the global attractiveness of that crypto.

I don’t have a crystal ball and of course I can’t say this will definitely happen. But I think it’s plausible.

Mask regulations in the parts of Europe that I’m familiar with were largely followed.
