Absolutely incorrect. A market is just any structure, place, or mechanism that allows buyers and sellers to exchange goods, services, information, or assets. There can be one seller and many buyers, one buyer and many sellers, or anything in between.

If I go to your stall and coercively take a product you want 1000 tokens for, but only leave 10 tokens. Then it is still a market? It certainly fits the definition you present.

Inwould argue that price discovery is a bit part of a market. Again, these things are already codified. Eg. Wash trades, insider trading, etc.
