Personally, I don't get pro-urbanization: it's crowded, loud, smelly, and for all that wondrous enjoyment (and more), crazy expensive. I like not being able to see/hear my neighbors and for them not to see/hear me. I like that my views are very pretty. I like that the noises I hear are nature, and not man/machines. I like that I get to spend more of my money on things other than rent (other things are cheaper in the 'burbs too). And to someone else's point -- I live in a city, but looking around, you'd never know it.
But maybe I'm just weird.
