What exactly is the difference between your "self organizing communities" and the cities and towns we have today? Nobody is forcing you to live in a city, you are free to move to any other city in the country.
Cities of millions of people are too big to effectively be a self organized community, imo. And I have moved to a city or town that operates closer to my ideals.
But the other thing that's important to remember is that those communities need to be organized for the well being of all, and there aren't such places today.
Also, there's a practical element. Capitalism is here and powerful. I still need to eat, so I participate. I just also spend a lot of time and money on mutual aid (I have a spare house I rent at "cost of maintenance" to families in need, because I believe housing should not be a commodity. Do I take what I can out of the capitalist mode and put it into the anarchist mode.)
