I have a lot to say 🙂. I kinda agree, but calling it a problem of "the left" isn't helpful. Left vs right is losing more and more meaning, and some of the most "left" people I know (woke, trans activist, anti climate change warriors, supporters of public healthcare and public transport...) are also experts on money and the financial system and understand price signals and so on And some of the biggest (financial) idiots I know are the "right wing" bitcoiners, who never studied economics in any way before bitcoin and who don't study anything outside the Bitcoin bubble. Pure pleb slop I think you're trying to say that, even in an optimistic Star Trek post-scarcity future, there will still be limits on usage and energy use. Do we build indoor ski resorts everywhere? Do we Terraform Mars? Do we build a Space Elevator? Individuals will de facto have an energy budget, and you rightly point out that money is the only sane way to both distribute resources (not necessarily "fairly") and to give price signals which encourage efficiency.
