You should distinguish between capitalism and anarcho-capitalism. You being a proponent of the latter would probably claim that no capitalism is true unless it is anarchistic. But this is not reality, only wishful thinking.
Truth is there has been no significant capitalism so far without a big state-like power above. Big corporations can only grow because of the state. The state is like the power environment (like mafia or war lords) who ensures contract fulfillment between individual entities and thus enables big private property. Without it, to-be-capitalism creates it's own super-monopoly in order to grow further. The mafia is in fact a state within a state, and some people even appreciate it's law-and-order. The mafia has grown naturally from the originally decentralized people. Consequently, an impressive shadow-economy became possible within the mafia power structure.
And of course the government army is helping big corporations. They are doing so all the time with free-trade agreements, wars, secret intelligence, imperialism, geopolitics.... Eventually big corporations become so big that they control the state, that's why we saw "too-big-to" fail. Mussolini was not only fascist, he also was capitalist (corporate-fascism).
And you definitely need to learn more about pre-history. The paleolithic social model 30000 years ago was the horde, which was basically an extended family. The superordinated unit was the tribe. It still exists today in some remote places like Amazon and Borneo. You don't want to tell us that they live less free than under Hitler and their women are being always gang-raped, c'mon.
