Here is a quote that might fit your request.

"Medieval Iceland was almost a purely free market society, even the law arose from private courts and from law making bodies which could literally be bought at a price. They still had a "state" but it was disconnected from geographical location and was in a sense voluntary since the people could freely choose which "goddard" (spelling?) to protect him. The poor, if they were aggressed against, could even sell their claim to a more powerful person who would then pursue the compensation for his own benefit. So it provided an extremely effective check on power and protection of human rights. They lasted 300 years before their first civil war (eventually the various set regions were monopolized), but they lasted an impressively long time and had a body of law that was extremely rich and complex. David Friedman compares Medieval Iceland to Athens in terms of cultural development.

However, because they still had in some sense delegated authority (although technically it was voluntary until it was monopolized) they eventually had internal conflict. It is an amazing testament to how stable a free market society could be, even considering that the Vikings were pretty much brutes! Just think what America could be like if it were purely voluntary! It would be incredible.

Down with the state (and sorry, but that includes the Constitution)!
