Libertatia>  "It strikes me that the an-cap vision being presented here makes the freedom of the market primary, and the freedom of individuals secondary."

No, you have it backwards.  Freedom of individuals is the primary; freedom of the market is simply the application of freedom of individuals with respect to production and trade.

Libertatia>  "Anarchism has never been whatever remains in the absence of the state"

Right. Anarchism is the philosophy with the goal absense of State.  Of course, anarchists can have other values, too.  E.g. We have various additional values which we want in addition to no  state.  But statelessness  is the primary and defining value of anarchism.

Libertatia>  "No capitalist I know of espouses capitalism on a moral basis ..."

??? Rand, Rothbard, Hoppe, hell, just about every anarcho-capitalist I know bases it on the NAP (non-aggression principle) except Friedman and Narveson.

Libertatia>  "... on the basis it "knows" what is best for everyone."

Right. We generally abhor utilitarianism, but of course that is not the only moral basis. We tend to prefer Natural Law rather than utilitarian moral justifications.

Libertatia> "Capitalism, like evolution, is nothing more than a blind algorithmic process, which tends to have a certain effect in terms of efficient allocation of resources. It is entirely agnostic, of itself, to "what's best for the society", or even whether there is a society..."

Right on. We see society more as an ecosystem with emergent order, as opposed to the statist view of society as a machine to be fixed by some imposed planned order.
