Yeah, but as POTS revenue declines in big cities, too, there's a tipping point beneath which it's not worth maintaining that infrastructure, either. While the unit economics are better because of the density, there are also more subscribers to serve, breeding its own infrastructural complexity. It may be more efficient to do it in cities per wire distance or unit of infrastructure, but there's also just more infrastructure. For POTS to be economical anywhere, a sizable chunk of the population has to buy it. I don't know what those tipping points are, but you can be 370% sure the ILECs have calculated this out meticulously.
