I believe that I said in an earlier comment that I'm not a fan of bans. This is just a funny meme, which serves as a good jumping off point for discussion. Rather, the policies that I am suggesting here (user pays, essentially) are one mechanism by which urban sprawl could be fixed, without government bans or mandates, respecting individual choice. There's one heck of a lot of land devoted to driving and storing cars that people could easily and quickly convert to housing, food production, and other necessities of life.
