BTW there is something I don't get in this whole RBE/Zeitgeist/Venus thing. In a post-scarcity economy, why would you need a political system to distribute resources?? Isn't that contradictory? People (sometimes) need to ration things precisely when they are scarce. If there is no scarcity, why don't you just let people build whatever they need when they need it?
The post-scarcity label comes from the labor theories of value. The story is, when you don't need labor to produce stuff, value goes to zero. It makes a lot of sense from the perspective of LTV, but I think it ironically proves that LTV itself doesn't make sense. So, yes, you will still have to distribute resources because they are scarce from an objective economical standpoint.
I have discussed this with hard-core Marxists a couple of times. In my opinion the problem arises because labor is ill-defined. I'm not saying it can be done better by the way, that's why I've scrapped LTV from my mind a long time ago.
