Is there some idealistic "utopian" form of economics that theoretically would work in paridise, but is unachievable on this earth? I'm not talking about communism or socialism, but rather, could a community of Christians, with different skills, be able to supply everything that a town needs? If money lets economies grow, outputting more than was put in, could the same thing be achieved in a small settlement, with a couple dozen people and no money?
Yes, even a pure marketplace economy is utopian. At one point I caught myself saying "pure capitalism has never been tried" and I realized how naive I was in assuming that only socialists were being pie in the sky utopians.
