A family is completely different.
I have a large family, this is nothing like even a functional family. Nothing.
I have lived in over three intentional communities (some others were too casual). From elaborate roommate situations to full on company town.
Working and living together in the “Epicurean dream” is intentional community, one lost to main stream awareness. And that is a form of excellent living!
I guess there are those who find living and working for others the natural way, and those who would live and work for themselves (as a community).
