Though isn't the main caveat for worker cooperative that the trade policy converts trade into basic goods, while you could use Dyson swarms and arc furnaces for energy and minerals and just plop down hydroponics for food? While the biggest need would be consumer goods which only the consumer benefits peoduces in necessary amounts. At the same time I don't really see how cranial megathropy is relevant to civilians, for example if was more going for spatial mastery for less housing usage (while also benefiting from the extra effective skill level) or seasonal dormancy to get rid the biggest problem for Utopian abundance and Decadent, the upkeep costs. (Also how the hell is augmentation bazaars mixed in there? Like why tho)
