What can I say except that I hope you're wrong about food production? The allotment system in the UK is a good example of this, and could be expanded on to good effect for the overall goal of more mutually supportive communities. Obviously we're not going to turn every city into homesteaders, but reducing the imbalances in our economic systems is worthwhile.

As for CHAZ/CHOP, I find it more useful not to judge it based on whether an impromptu short-lived anarchistic community can govern itself perfectly during that chaotic moment in time (especially as police had every reason to try and subvert it - after all, they did lose that precinct), but based on its vision and the hope it gave people. It only lasted a short while, but hopefully the memory of it can live on as a hope for what could be, and as a part of the dialogue between communities and state forces going forward.
