Why cryptocurrencies of all the energy hungry sectors? There are way lower hanging fruits than crypto.
If miners cannot sell their coins, they can't pay the electricity bills.
Bitcoin will always be around, but with sufficient fiat blockages the value plummets.
Governments should announce that people will have a year to sell all their coins (the price will tank immediately anyway), and then buying and selling of PoW coins will be banned.
Are you Kim Stanley Robinson? If you aren't you'll enjoy his latest novel "Ministry for the Future", which follows the line you describe and posits a post-apocalyptic future with less machine labour and more manual labour, abandonment of air travel, no meat consumption by humans, a solar array covering much of India, etc. He then proposes replacing Proof of Work with Proof of Carbon Sequestration.

Aside: MftF is, to me, an appalling unscientific low effort bit of propaganda (at least for the first 60 chapters) but perhaps there is a way to steelman KSR's theses.
Unfortunately, I think the only thing that's going to stop Bitcoin mining is the laws of physics.
People are gonna tell us (bitcoiners) that the USD is secured by the powerful military of US behind it and we're supposed to accept it as a positive, but if we say that we're going to use electricity to secure the network with nothing but math and computation, we're instantly hated by the same people. What gives?
How can you be ok with wars and threats of violence to enforce the value of a currency, but not computation and electricity? I just don't understand it.
* Most renewable/stranded energy mining operations have their own energy source that is not going to be shared by someone else.
* Bitcoin's energy consumption doesn't scale with the number of transactions on each block.
* Most of the bitcoin has already been mined, the incentive to "mine aggressively" is decreasing over time.
* "What if bitcoin uses all the energy", like the top poster on this thread was talking about, they were mocking it to say that all of the energy generated by the sun will be used for mining eventually, is this a fair argument? If such extremist thinking took hold, we could use it to subdue pretty much all progress. Did we think that there will be gold miners digging up land everywhere and we won't have a place to live?

They straight up want destruction, without even considering merits of the new technology.
The energy consumption in clothes dryers, transportation, christmas lights etc. all will fall under "more than most countries" category. You are just constructing a narrative based attack.
The dollar is literally backed by the extraction and sale of oil (for dollars), which itself is enforced by the largest consumer of oil in the world, the U.S. military, and they secure the trade routes with their aircraft carriers and subs. It's called the petrodollar for a reason.
I'm not dismissing criticism, I'm just questioning your line of criticism. Everyone will accept a fair regulatory regime, many of you are calling for an outright banishment, that's unacceptable.
