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.
The powers that be will likely push for cashless society because it gives them more surveillance & control
If credit/debit cards were the norm and cash was invented today, it would likely be outlawed down because criminals/terrorists/child kidnappers will use if for nefarious purposes
