> a completely free market

Is a 'completely free market' if not a spherical cow in a vacuum on a frictionless surface i.e. a purely theoretical concept that can never exist in real life?

Presumably a 'completely free market' allows cartells, bribes are not illegal, and there is no authority to throw me in jail if I lie about my product? So either it would collapse into a cesspool of fraud, or you have to introduce rules and then it's not free any more?
