Allow me to go point by point.
1)Governments are parasites:
Government spending is a portion of GDP which means that resources are not destroyed by the government, merely reallocated. Additionally, they address externalities which could not be handled by the private sector. While the proper scope of government can certainly be debated, and I might agree that it is currently too large, to dismiss all governments as parasitic is incredibly ignorant.
2) Governments have a monopoly of force:
There are currently 192 governments, which is no indicative of a monopolistic market. Rather, it in indicative of a competitive market with high entry costs. It is true that a cannot individually enter the "force market". I also cannot build my own cars. This does not mean that car manufacturers are a monopoly.
3) Countries are controlled by central banks:
First off, this isn't true. Second off, who cares?
