One thing Venus Project is right about is that superabundance relative to today is possible, or should be at any rate. If they propose to have an computer that builds up anything that people ask, then sure, nothing about that idea is inconsistent with the idea of capitalism or of human action so long as they are not saying that capitalist acts between two consenting adults will become illegal. In this scenario the god-like computer will simply be fulfilling the role of a "super entrepreneur".

Eventually prices will be cheap, but prices will still exist. Even if a car becomes very cheap to build, it does not follow that each person will be able to own 50 000 cars each. So long as the universe is finite then there will be prices, and this is not something imposed upon us but rather something that follows as a necessary consequence of the fact that there is real scarcity in the world and there always will be, land is not homogeneous and neither are people, and each person has a different set subjective values. You cannot centrally plan knowledge that only exists inside the individual, like individual preferences and how they interact to allocate capital via the price mechanism.

Again, I see no reason why a "super entrepreneur" type of computer could not exist so I don't deny that. I don't think we're there today but certainly I can only imagine where we would be if not for all of the waste and misallocation caused by wars and central banking.
