If cellular data services were not capped (or throttled down, past an imaginary line the phone company rarely shares), then you might have an argument. As it stands, 4g phone service is only a replacement for cable or dsl services for the rarest of individuals. Windows software updates alone will blow you through your cap.
You're looking backwards through time. Look forwards through time. There are all sorts of ways the last mile problem can be solved more cheaply than wiring up every household, with high network speeds.
I see all these "can be" and "could be" type statements, but the reality of the situation is that we have not solved these problems yet, but today we have no net neutrality regulation. So it's ok to think of the bright future 5 years (optimistically) down the line while we've immediately taken a huge step back?
