Cops are one example of unjust hierarchy. They enforce arbitrary rulings, using violence, onto individuals within society. Many of these rulings are on events that would have had no impact outside of that individual, drug charges for example. Ancaps see this as bad, because it's the state forcing people to do things. But then that completely flips around when it's a business. The free market will sort it out right? Just move to another country ancaps, just move to another country. That's all you have to do for freedom. There is no difference between a country and a business. The majority of the 100 biggest economies in the world are not countries, but businesses. I can assure you that within those mega-corporations they have a bureaucracy, not a free market.
What? Not all of you ancaps can afford it? You should have thought about that before being born without money.
