Thank you for the answer Mr. Casey, I’ll think and read about it some more and maybe post an opinion here. It seems to me that this question has to be resolved, or very seriously addressed, in one way or another.
Both Mises and Hayek seemed not to be believers in a good anarchy being practical, and as D. Friedman said that difference of opinion between Milton and him was that one thought it might work but probably can’t while other thought the opposite. All these extremely bright (and largely well meaning) people are like a dark cloud hovering above the whole idea… why wouldn’t Mises be more explicit and say clearly why he thought some state remainder is necessary? Anyway, this national defense question maybe the watershed.. for one to make a final opinion on the matter.
