This isn't a good situation, but I also don't like the idea that people should be banned from using energy how they want to. One could also make the case that video games or vibrators are not "valuable" uses of energy, but if the user paid for it, they should be allowed to use it.
Instead of moralizing we should enact a tax on carbon (like we have in Canada) equal to the amount of money it would take to remove that carbon. AI and crypto (& xboxes, vibrators, etc) would still exist, but only at levels where they are profitable in this environment.
It's anti-tech propaganda. The same is happening with crypto. Certain groups don't like it, so they try to convince the public that it is bad for the environment so it will be banned
