A true free market is where someone can hold a gun to your head and make you pay them whatever they want, and you gladly do so because you got rid of all the police who could stop them. In a true free market, the guy with the biggest gun and the most money can buy everyone else out, so that he now has a complete monopoly.

You don’t really want a true free market. You want a market with full price transparency. You want a market with lots of competition, and where no one in the market can get an unfair advantage over anyone else. And that only happens if it is a well-regulated market, which is a lot like a well-regulated militia.
