I don't think I follow your reasoning tbh. What exactly are you comparing? You said that capitalists favour intervening governments, which is simply not true. Not in any general sense anyway.
Anarcho capitalism is probably as far into anarchy you can go. They want to completely abolish the state and enforce property rights privately.
Or are you saying that such a society will fall into some kind of feudalism? At the core of anarcho capitalism is the NAP which is not really compatible with feudalism. In feudalism you have a hierarchy not based on voluntarism, and that would therefore not be anarcho capitalist.
Do you imply that we need a strong state with a monopoly on violence to keep us in check, otherwise we would descend into chaos? Thats a pretty bleak and pessimistic view of mankind.
