I dislike the all or nothing aspect of a lot of them. It is hard enough to nail a single aspect of life. So imho it is better to have different groups for different aspects. As in you might have a housing co-operative, a co-operative work place, a utility co-operative, a bike sharing group and so forth. That makes it possible to not go and avoids being stuck in a group, which you really do not like. As in it is much easier to move to another place, then to do that and find a new job, organize transport and so forth.
