I recently met an interesting woman named Susan Love Brown. She told me about her research on intentional communities, which I found fascinating. Intentional communities can be anything from religious sects to cooperative sharing arrangements. But they typically share one feature in common: voluntarism.
Recall that in Ten Things Leftists Should Know about Libertarianism, I mentioned the fact that community and compulsion often get conflated, which is to say government power does not equal community, nor even is it terribly conducive to it in a Tocquevillean sense.
For me, it all boils down to a right of exit (and perhaps also a right of exclusion). We can have all manner of experiments with intentional communities (that include communal redistribution, work-sharing, cooperatives, and the like), but that are not based on compulsion. Nor must they be controlled by elites, which is counter to the spirit of egalitarianism anyway.
So the question I will leave for my leftish friends is: if in a situation that is far freer than what we have today both in economic and personal terms, why is it that a pluralism of living arrangements is a bad thing? Why must your idea of community and society be directed by coercive elites? In a libertarian system, all other systems can be subsumed. In a statist system, we must all live with the choices of the mob (democracy) or of state elites (oligarchy), or both. Why would anyone find this desirable unless the sole motivation for that position is guilt or envy relative to the economic station of others (and a fetishization of power)?
With intentional community, you can criticize by creating.
(Update: The founder of this intentional community was an Explorer's Foundation Cobden-Bright award winner in 2007. Explorer's is a small philanthropy devoted to understanding of "free order." Check them out.)
