Bitcoin isn't going away. More people are putting their trust in it as their monetary standard every day, not less. Bitcoin, the asset and network are neutral. Scams on top of it, shitcoin affinity scams, or whatever "oodles of other great reasons" don't change that. The majority of Bitcoin mining is already renewable, it already incentivises renewables this isn't a hypothetical future.

If somebody proposed a law tomorrow that bans coal plants being reopened to mine Bitcoin I wouldn't be against it, and Bitcoin would carry on happily regardless.

BUt you're then getting into the dangerous territory of telling people what and what isn't an acceptable use of compute power. Bitcoin is a valid and useful consumer of energy.
