The system you are talking about sounds like a cross between a direct democracy and a post-scarcity communist society, if you've not read the works of Iain M Banks you should check them out, you are pretty much describing The Culture :).
Haven't read the others, but Red Mars is excellent, and better than Culture, in my opinion (though the latter varies in quality).
For another vision of a futuristic post-scarcity anarchist adhocracy, see James P. Hogan's Voyage from Yesteryear, which features less "magical" AI and is more of a reflection on cultural conditioning.
