I've read a fair number of articles like this about 'networks of friends' and 'mutual aid and support' and I always come away feeling like this is more like a description of a network of military alliances between independent city-states in ancient Greece than what I'd consider normal, healthy friendship or familial relationships. I've seen many human relationships fall apart because people expect too much from the relationships, such as financial support or emotional support or something like that. It's really too easy for such relationships to become somewhat exploitive on one side or the other. When people cross the lines between business relationships and personal relationships, things get messy fast.
