A pure laissez-faire capitalist society has never existed. The closest any country has come to pure capitalism is 19th century America. Twentieth-century America is not a purely capitalist country but is a “mixed economy”: a mixture of freedom and controls. i.e., crippled capitalism, i.e., a hampered market economy.

Capitalism is not utopian, but it is practical. The fact that 100% pure capitalism has never existed does not mean it cannot exist, or that it will not exist in the future; laissez-faire capitalism is a definite metaphysical possibility.
