You be the judge.
Roderick Long (aka "BerserkRL"?) argues against Tyler Cowen's anti-anarchism argument as follows:
"Tyler Cowen... said what happens is that basically this [system of competing protection agencies] forms into a cartel, and it’s going to be in the interest of this cartel to sort of turn itself into a government. And any new agency that comes along, they can just boycott it.... Sure. All kinds of things could happen. Half the country could commit suicide tomorrow. But, is it likely?"
Well, given that in every single instance, without any exceptions, where we've seen a state of anarchy or semi-anarchy in the past, a government has arisen to fill the vacuum, the answer is, very obviously, "Yes, it's almost a near certainty that Cowen's scenario will play out the way he said it would."
But, I know, in the imaginary trufry market, this would never, ever happen.
