The sort of freedom referred to has nothing to do with a zero-price. It has to do with the ability of two consenting adults (or we can say "willing parties" if you want) to enter into a transaction to exchange goods or services, or proxies (like dollars).

The opposite of such a freedom is not that one party chooses to charge for some of its services, but that one party is prevented from offering such a service.
