There are huge areas of farmland that could be cities. Which aren't ringed by (and hence, downwind from) mega-ranches? Or correctional facilities? Which have access to adequate water resources (already heavily constrained in many of these areas) to support massive human settlements? And close enough to lakes, parks, and other attractions so that people would actually... want to live there? Not so many. And the genuinely fallow areas which do exist should probably be protected as such, and/or restored further to their pre-cultivation state.
