Yes I agree, in a free market there would be no Corporation because guess what, a Corporation is a State entity.

Sort of like the 4th branch of the State: judiciary, legislative, government, corporate.

It is a state entity, and it is protected by the state and also used for law enforcement.

I oppose the concept of corporation too, and most anarchists, free market capitalists, voluntarists too.

In a free market, business is done through reputation, so the owners of the business are responsible for both profits (no taxes) and both the liabilities (no bailouts, legal shield ,etc..).

That is how a honest capitalist system would work.
