I just read Chaos Theory – Robert P. Murphy at mises.org . http://mises.org/document/3088
I think Robert P. Murphy makes a good case for defense in an anarcho-capitalism society, but I’m still sceptical, because I haven’t seen in history or today a real life example of it.
I have regret that I haven’t taken Robert P. Murphy course on this subject on Mises Academy. Because in my opinion he’s a good teacher and a very good economist. I have taken his courses Anatomy of the Fed, The State of the Economy and I just finished his course The Economics of the Great Depression on Mises Academy.
I also have read Man, Economy, and State with Power and Market, Study Guide – Robert P Murphy and Theory of money and credit study guide – Robert P Murphy.
