Rothbard makes a similar point, arguing, "Of course, some of the private defense agencies will become criminal, just as some people become criminal now. But the point is that in a stateless society there would be no regular, "legalized" channel for crime and aggression, no government apparatus the control of which provides a secure monopoly for invasion of person and property...To create such an instrument "de novo" is very difficult, and, indeed, almost impossible; historically, it took State rulers centuries to create a functioning State apparatus."
