I think money is largely the issue. I lived in several different 5-7 bedroom communal houses in SF with a bunch of founders/engineers and if everyone (or even half the people) have high paying jobs then it's a very different experience. The group can easily absorb months of another resident's rent if they have volatile income which greatly reduces the pressure on relationships.

It only costs a few hundred bucks a week to have cleaners come over and take care of the house so most chores are a none issue. Dishes and trash were the only rotating chores IIRC since those couldn't be put off between weekly cleanings. There was a fridge for personal food and a separate communal fridge with a group food budget so all staples were always taken care of. Internet, insurance, water, power, were all split equally. There were no problems concerning the money even though some people were messier, some ate at home more, some worked from home entirely, etc. etc.

That's a far flung situation from the one described in TFA though. We lived together to build a community as adults, not for survival. That changes the dynamics.
