The author of this new and excellent book is my colleague Peter T. Leeson and the subtitle is Why Self-Governance Works Better Than You Think. Here is one excerpt:

Twenty-two of thirty-seven street gangs Jankowski (1991: 78-82) studied have written constitutions. Sicilian Mafiosi follow a largely unwritten code of rules, and recently police found a written set of “ten commandments” outlining the Mafia’s core laws…Kaminski (2004) identifies extensive (yet unwritten) rules dictating nearly every aspect of Polish prisoners’ lives, from what words are acceptable to use in greeting a stranger to how and when to use the bathroom. And the National Gang Crime Research Center considers constitutions so central to criminal societies that the use of a constitution is one of the defining characteristics it uses when classifying gangs…

Peter of course does not favor criminal gangs, rather he seeks social principles for voluntarism and yes perhaps you could call these views a kind of anarchism. My stance, however, differs from his.

I accept the reductionist argument that government too is a kind of anarchy, since it must rely on norms and internally polycentric and perhaps even ultimately intransitive mechanisms for maintaining order. There is no “final court of authority” in the practical sense, but rather a series of overlapping constraints which give rise to a spontaneous order of rules and governance, for better or worse. In this sense anarchy is not an absurd idea at all, and we can imagine many varieties of orderly anarchy, including those in a more libertarian direction. That said, while I often favor smaller government, when it comes to political philosophy I do not seek to move toward “more anarchy.” In fact I often admire the relatively centralized governmental structures of Great Britain and New Zealand, with their clean and sharp lines of accountability.

I think modern anarchy would indeed be “orderly,” but I also think that private protection agencies would end up colluding and re-evolving into a form of coercive government (pdf), furthermore in a form that libertarians would find objectionable. I would much rather have the West’s current democratic governments, for all their imperfections, than a for-profit “shareholder state,” not to mention the transition costs and the uncertainties along the way. The best thing you can say about a shareholder state is that it might have a better immigration policy. In the meantime, we are seeking to rebuild the history we have.
