Right, those are the current technologies we have to make markets work in a particular way. They don't preclude other technologies which work with freer markets.
Like there's a whole zoo of healthcare provision approaches, for example. Single payer can work fine (ala Norway), but so can Bismarck (ala Switzerland). The latter is a technological architecture that _enables_ similar or better outcomes, while being closer to a fully market-based approach.
But climbing a hill does make you closer to the moon. There's nothing wrong with incremental progress towards a goal, assuming this is a goal for the free-market people.
Also, I'm not sure a free market is technology-free per se. What you're talking about is specifically ancap-like, but most free market frameworks involve a state actor that should (among other things) not allow for itself to be weaponized against other market participants.
Like the paradox of tolerance, you can't tolerate a free market for bribing your way to benefit from the state's monopoly on violence. I don't think the existence of this paradox destroys the value of free markets or tolerance.
