You're saying I should go live in the countryside, away from everyone? Yeah, teleconferencing is possible, but I don't know that most people would want to.
It's also impractical to build public transportation that far out (you have to build increasingly more for each mile you expand from the nearest city center; distance between angles grows as you move outward), meaning that people would be driving a LOT more (higher gas prices). Or, if you by some miracle built all that transportation, it would be expensive. And people still need to "go to town" for many supplies, so just staying there isn't practical (let alone realistic for most).
