> free market systems are the only feasible economic system
Free market systems are not feasible, and capitalism (a system defined around description of a real, at the time existing, system) is not a “free market” system (an infeasible abstraction invented as a post-hoc rationalization for capitalism.)
We may have a terminological difference. When I said "free market", I don't mean a lasseiz faire market/capitalist system - I mean something similar to what the US has now, where money is a Thing and producers sell to consumers, but the government steps in to regulate around negative externalities, prevent harm to consumers, and keep the economy stable.
What are your definitions of "free market systems" and "capitalism"?
