I definitely like these ideas and would love to see them explored more fully. Currently I am working on moving to the Midwest in order to purchase a large plot (100+ acres would be ideal) to set up a farm. After that, the goal is to start moving others in to create a sort of intentional community. While on a smaller scale than a city, I am still hopeful what this will provide a real world example for others to point to when the inevitable "Anarchy can never work!" crowd starts up with their naysaying.
