I don't know. Rural areas have farms, and there are plenty of government regulations about farming - and your money is tied to these. Government is less convenient too: Just a trip to the DMV or courthouse might take 30-60 minutes of driving.
I think the parent was correct: Cities tend to have more diverse populations. Rural areas tend to have less, which means less folks to challenge your notions of the world (and more chance that you'll write some of the folks off that do so).
