I never claimed free markets were utopian. The purpose of government in a free market economy is to provide justice for acts of force or fraud, and provide enforcement of contracts.
There is no such thing as a perfect free market. However, history shows that the closer we are to them, the more prosperous the country is.
BTW, when the Soviet Union was formed, the communists did away with the police because there would no longer be a need for them. Oops.
