When I ask google "what is a free market?" I get:

"A free market is an economic system where prices, production, and distribution of goods and services are determined purely by the laws of supply and demand, rather than by government intervention. In an idealized free market, buyers and sellers voluntarily exchange goods, and competition naturally drives innovation, efficiency, and fair pricing."

That's what I'm talking about.

The wikipedia Perfect_competition reference does not mention "free market".

Google says Adam Smith never mentioned the term "perfect competition".
