My intent is to make this a "content blog", and I'm resisting the temptation to link to every web site or news event that I find interesting. That said, I've recently stumbled upon http://www.cooperativeindividualism.org/. Very well presented writing and instructional materials on a theory of human organization roughly based on the works of philosophers such as Thomas Paine and Henry George. I found it especially interesting that the author (Edward Dobson) was able to effectively criticize the tendency of the modern concept of ownership (especially of land) to lead to heirarchy and stratification without simultaneously supporting statist socialism.
Dobson presents some excellent ideas that address the fundamental flaw of anarcho-capitalism and minarchy: that an unfettered free market will inevitably lead to intensification of centralization and stratification of power, returning ultimately to an oppressive state structure.
