>This idea they have that private enterprise naturally evolves toward the most efficient system is laughable.

This is a straw-man, nobody claims that private enterprises are necessarily more efficient than government organisations. What is claimed, however, is that a free-market system invariably leads to better processes and products, compared to a government monopoly, because there is a competitive advantage in optimising overheads.

To suggest that government organisations are "often" or even "occasionally" more efficient than private organisations is quite chuckle-worthy.
