With the shrinking availability of resources (esp. housing) in many places, I have wondered if, in the near future, more people will create these ad-hoc extended families rather than sticking to the normal 2-person couples. It'll require people to let go of the idea of monogamy though; arrangements like these probably won't work if monogamy is expected, because with so many adults living closely together, it's inevitable that attractions would happen, so the whole thing would only work I think if people are allowed to explore those without everything blowing up. But on the other hand, finding just one person you like to live with is very challenging; throw in just 1 or 2 more and it seems almost impossible (i.e., the extra people have to get along well not just with you, but with your current partner, and any other new people as well). So yeah, theoretically having 6-20 adults all living together and sleeping with each other sounds fantastic when looking at resource-sharing and time management, but when you think about potential personality clashes it seems impossible to me unfortunately.
