http://analyticaleconomist.blogspot.com/2013/06/anarcho-capitalistic-dogmatism.html"Yet another problem is the Neo-Austrian/Neo-Rothbardian anarcho-capitalist rejects model theory in economics because they believe that models cannot properly capture reality. So for example, the perfect competition model shows what an economy would look like given these assumptions:
Infinite buyers and sellers
Zero entry and exit barriers
Perfect mobility of goods and services
Perfect information
Zero transaction costs
Profit maximization
Homogeneous products
Non-increasing returns to scale
Property rights
All economists realize that these factors do not exist in real-time but nonetheless, it is a theory that can be utilized for advancement of a free society.
Neither Mises, nor Rothbard were assuming ideal conditions. There was a thought experiment of "evenly rotating economy", but it is only to investigate several ideas before applying them to real world situations. Both of them considered how coercion and other various real human actions change economic structure (Rothbard in a much more detailed and structured way). None was advocating any separate macroeconomic theory. Everything was discussed on a level of individual decisions (micro-economics) and how it may lead to some big-picture patterns.
Anarcho-capitalism, first of all, is non-agression principle. No one proclaims how society should be "modelled" or function. The only idea is to never allow institutionalised violence as a method of "solving" problems. Then, in absence of federal mega-mafia, people can figure out how to live their lives, how to protect themselves, how to communicate and how to resolve conflicts.
I don't see anything "dogmatic" in applying everybody's desire to live in peace to ALL activities in society. Dogmatism is what all other philosophers and politics use when trying to excuse their desire to apply force to achieve their ends.
