Is there a level of support of government that one can have and still be considered a good advocate for liberty?
I think this issue stems from the confusion between govern
ment and govern
ance.
People accept governance over their interaction with others, voluntarily, constantly. The store with "No Shirt, No Shoes, No Service" is placing governance upon those who would enter the store. Those who enter are voluntarily agreeing to the "terms of service" in order to do business there.
We accept governance in every association, every group, every interaction. That is why (protests to the contrary notwithstanding) anarchy is not chaos and does not "turn into bullshit in a matter a days". People come together peacefully because people survive better in cooperation than they do by eating their neighbors.
Minarchists tend to be convinced that there is(are) service(s) that MUST be provided by government because they are not provided by market forces. This ignores the fact that those services are in demand. Police, adjudication, and what else, roads? All have been and even today are provided privately.
What govern
ment creates is chaos. Constantly shifting laws, inconsistent enforcement, absurd punishments for what constitutes no crime at all, special favors for arbitrary individuals or groups, etc. All subvert the natural governance which arises between individuals.
