People need to stop thinking about the free market as some kind of oracle. It's not. It's a collection of feedback loops between greedy optimizers. It drives people down the local gradient of profitability, which has only a minimal relationship with long-term social utility. It can, and will, drive us all off a cliff if there's enough money to be made stepping off the edge.
And yes, I'm with you here. I just don't see it as society deciding. If asked, most people will also be baffled how it is you and me get more than a climate scientist or a nuclear engineer. They also can't directly express their individual preferences on this using their wallets, because the market isn't structured in a way to allow that.
