I agree with you that proof of work is a disaster. The problem is that mining is probably the last part of modern cryptocurrency network that will go away following a full-on regulatory onslaught. What will instead crash first are the newer and less-resilient networks that don't use proof of work: proof-of-authority systems like Cosmos/Polygon, centralized systems like Binance Smart Chain, all the scalable rollup servers. Ongoing transitions like Ethereum's move to proof of stake might also be disrupted. Even if a regulatory approach was ultimately successful in shutting down proof-of-work mining, I think it would take years. Those years could be better spent by devising and encouraging more efficient consensus technologies, like the ones already being launched today.
