> What is not a free market is

A bit of a tangent, but price transparency is another factor.

At least when economists publish their "it's the bestest and most efficient option" analyses their definition involves perfect information: No secret prices, no non-disclosure agreements, everybody knows what was paid for inputs and labor, etc.

I bring this up because there is an unavoidable conflict between "the market that moves freely as a whole" version versus "the market where I'm free to keep secrets."
