if i'm getting it right, it makes sense. say there's enough food for everyone (and water and air, naturally). and given that there's a nice slice of punani for us, there's technically nothing else you need. then, given that an infrastructure has been created (of course with a lot of money, ironically), all you would need is resources to continue technological developments, as social advancements solely require minds.
if the venus project became large enough to obtain/create these resources within their own system, (say the venus project idea becomes the whole world's basis in a millenia, for an extreme example), then you wouldn't have to pay for shit anyway. people don't need the money to live. and it would be mechanised, too.
pretty much all you'll have to worry about is to make sure you keep the crops growing, and the kids educated. (im assuming that due to lack of jobs, adults will just keep learning, too, while having sex and smoking hallucenogenics.)
it's a bit of a fantasy world... or is it?
of course shit could go wrong. but it'd be nice to live in a place like that. you'd want to help rectify the situation.
but i don't think it would or could go ungoverned.
