That’s so reductive that even Keynes would probably take issue.
Discoverability is the axis of competition in this context, not price. The market has not effectively found out how to identify quality in order to price it, so externalities rule instead: pre-existing authors with recognizable names, whatever genre publishers like at a given moment (famously disconnected from what people actually want to buy), how many energy drinks a crabby editor has had by the time they get to your manuscript, and so on.
Search engine and recommendation systems were supposed to ameliorate those externalities. They didn’t.
Something tells me that doesn't alter the value of the art as expression of the intention of the artist, and not the assistant be it human or machine. In the spot painting case he was deliberately playing with this idea to the degree it added to the perceived value.

I still have to see someone using LLM to share a soulful vision of his.
