Living outside a conurbation doesn’t mean you don’t still need access to the amenities there. You still need groceries, to get kids to school, to visit the doctor, or even maybe visit friends, either in the city, or somewhere else outside it.
That's an urban lifestyle.
Not that I blame people who live out in the sticks and commute into the city. The roads were there first, after all, and they're taking advantage of conditions. It's just a net-loss for society, and as is becoming clear, isn't sustainable.
