In 5 to 10 years, the FCC will change and so will most of DC. You can't say they're setting them up.
The thing though is, its expensive to build your own network, COX already found that out along with many other companies, why do you think VZW is mostly put together smaller companies along with AT&T Mobility? The cost of rebuilding those networks and such costs tooooo much for anyone to take on right now unless you build out a fully complete network and still will take you several years to get where AT&T and VZW are today. Hell, even Sprint can't keep up, but then again they could have started years ago.
