A "free market" that accepts violence as the means of competition isn't free, or a market.
Call it an evolutionary soup then. Just like slow gazelles get eaten by jaguars and thus gazelles are evolved for speed, non-state societies fell apart or were conquered and modern societies evolved for security and stability. Even if you don't like it, that's how evolution works. A gazelle does not get to say to a jaguar "No violence please" does it?
Nope, but they do have some nasty horns...
