Maybe these communes can be run like social networks, so you don't even have to worry about how people smell, as long as they contribute and don't screw up big time.
They could even compete against one another to offer better "benefits" for less work. It's a much sunnier proposition than forcing the billions of people who need to eat to compete for an ever-shrinking pool of un-automatable work, wouldn't you say?
Food production and food science are advancing and it will only accelerate. Currently, technologies like aquaponics allow for high volumes of nutrient rich foods to be produced with much less water and fuel inputs. In the future we may be able to print food. At that point, you don't really need to be employed to survive. An unlimited supply of food for a person will be as cheap as a stocking stuffer.
