alt Hacker NewsAIUI David Graeber famously pointed out that people in small groups can form the equivalent of a "market" simply by exchanging favours ("I'll scratch your back if you scratch mine") in an informal gift economy, without any money-like token or external unit of account. That's quite in line with what I said.
You understanding is mistaken. Graeber's "everyday communism" is not a market, and his whole larger point is that contorting everything to the lens of markets is simply ahistorical and unempirical.
I'd strongly suggest reading his books. They profoundly changed my understanding of how human institutions and society form.
