When two incomes are not sufficient to live somewhere. When it takes a town to raise a child and the local town is ... cruel ... When people get less attached to mythical ideas like "nuclear family" (which is a pretty modern myth), or like the myth of "man and woman" as only model to a family. That some of the really old male-centric cultures are coming out more visible with polygamy, along with some of the "free love" movement and their crossover with the libertarians with (eg) Heinlein's "Stranger in a Strange Land" ideas, well that's likely happening too. I think a lot of reasons people explore this. Likely multiple often. All of the sustained groups I've encountered though have been mixed, distributed and really supportive of both each other, and others. A joy to be around.
