I can't recall whether I have told this before. What Gaetan seems to be asking is whether or not any of us would be interested in joining a commune. Some might, but this is a far different thing from asking whether we believe a communal system ought to be made universal.
Long long ago I worked for an "intentional community," basically a small version of a commune, in this case serving mentally handicapped adults. No salary, but one's needs provided for. It worked pretty well, but it was not run as a democratic enterprise. The administration was in charge, and was not run communally. The structure was somewhat complicated, and the presence of many persons for whom useful low level work was fulfilling made some aspects of running a community relatively easy.
We occasionally were visited by people from other such setups, exchanging information and the like. At one point we had some people from a community (still in existence, but much changed since then) which had decided to take the fictional utopia in B.F. Skinner's Walden II as a guide, using the book itself as virtual scripture. In this arrangement, everyone was expected to produce a certain amount of labor, the value of which was fixed according to a formula. Each person was expected to earn a certain minimum number of work credits, with worse jobs paying better. Of course any job that was considered at all necessary must be possible to perform in the time frame, so the difference in credits could not be astronomical. But people were free to choose what to do. There was no central administration dictating that the community needed this or that job done and assigning it to anyone.
It did not take long for this system to fall apart, because people realized early that they'd rather do a nice job for twice as long as a lousy one, and if they just didn't feel like doing something, nobody could tell them to do it. So the sheep kept getting out because nobody fixed the fences. Nobody could say "you must help fix the fence." You could up the pay, but if you got your living well enough doing something else, the pay itself was worthless.
One is reminded here a bit of a commentary Slavenka Drakulich made about the problem with Yugoslavia at the end of communism: it was a country where everyone had plenty of money and nothing to spend it on.
The community itself made a living by making hammocks as I recall, and I believe they still do. But I don't think they're Walden II fundamentalists any more.
I like the idea of eliminating poverty and excessive privilege and greed and all that, but people are people, and it's hard to get people to do what they must without some kind of motivation, and people's needs and desires are not uniform.
Of course an intentional community is a special case to begin with, since joining it is voluntary. Economic ideas that work for a self-selected group may not work nearly as well if they're imposed.
