In a truly communal society, discussions about such topics as sex toys would not be taboo but rather approached with transparency. And I disagree that economic incentives are necessary to unite people. Solidarity can be based on shared values and mutual aid within a decentralized, non-capitalist framework.
@Radical_EgoCom According to anthropologists, one of the human universals practiced by all cultures is that sex is done in private rather than public. "Realistically," there would probably be other taboos that people wouldn't want to discuss with their neighbors, but might be willing to transact with their dealers.
