Why is the Eden project a good idea? I get that society does need proper balance in certain sectors and jobs but that's pretty well handled by people just doing what they want to in terms of profession, so discontinued the population to become housewives while the other half have to work, you end up creating a society that is incapable of functioning without one of the two halves, which would really suck. By using a much more free system in which anyone can do whatever, you don't have to rely on any one group of people and can instead prosper from the work of society as a whole.
