I liked the work he did. I partially agree with you.
The Venus project failed to model negative human behavior and instinct. Using the socialist fantasy in place of money is a pretty thought but flawed in more ways than it worked.
I have done conceptual work on the elements required to de-monetize components of society. It is complex but it appears to be conditionally/contextually solvable and it seems to be a good goal. The unmetered aspect present when you experience the fullest sense of freedom is antithetical to the nature of money. While zero money, i.e. all aspects of society de-monetized, may not be sound even in theory, I assert that a society with more free aspects is better than one with less.
