The truly free market might work as described, I am not contending that. But history repeatedly shown that free market is an unstable equilibrium prone to exploitation by organized groups.

History has more accurately shown organized groups use government to destabilize the free market in a bid to control it.

The solution to this, something the framers of the US attempted, is to deny government the authority to do this. Unfortunately we did not listen to their warnings and have since at least the end of the civil war, and more accelerated since the Great Depression have removed these limits from government, have rolled back the separation of powers. altered the very foundation of the US Government and allowed more and more power to become centralized, this as enabled the very wealth and income inequality that people now want the government that caused the issue in the first place to "fix", this of course will fail but supporters of government solutions to all problems will never admit that the government is the problem...

As the axiom goes, Government: If you think you have problems now, wait until you see our solutions.

And if you think there's nothing worse than government, wait until it fails.

Seems you never saw anything outside US.
