Personally I'm a fan of a workers run syndicalist economy. There are other options, like a workers run market economy, or an outright collectivist gift economy.

Of which we already have a great example in FOSS.
Which is utterly dependent on the "real" economy for umm, food and every other essential.
The question is, how would you enforce that, if some part of the populace just decided to recognize property rights, and structured their part of the economy accordingly?
Are there any examples of that working at large scale?
