I see what you’re saying, but it’s just not true.
Trade takes the form of exchange of the rights of ownership, and this is a right enforced by government.
For example, if I own a house, the house doesn’t care who does what. The owner is the one with the right to call the cops if a non-owner comes in unwanted. This instantly becomes an appeal to violence and the government.
This is even more true in the modern sense of the free market, financial markets exchange very little actual physical goods, the thing being traded is rights to contracts, rights which are guaranteed by the government regulator.
The only place this isn’t quite true is with blockchain based assets.
