They also have to get radio spectrum for the uplink everywhere they operate. Have a good look through the history of Iridium (Iridium PREVIOUS?) and all of the unexpected costs Motorola ran into building and maintaining a satellite fleet.
If you go to the middle east and many third world countries much of the Internet is still satellite. If a particular country wanted a way to insure that they still had access to most of the world's internet traffic (as economies grow and infrastructure is built) they might prefer a constellation of LEO sats capable of carrying the entire planet's traffic in a point to point fashion owned by a US based company who is very reliant on the USG for most of its other business.
But would they want this to exist enough to pay for any of it or have a hand in maintaining it? Beyond how much they already are by awarding SpaceX government and NASA launch contracts?
And all because muni government sucks.
Now, the costs of these satellites and receiver's will make or break this idea. But, it's surprisingly viable even if they only cover the continental US to start.
PS: Iridium NEXT (https://en.wikipedia.org/wiki/Iridium_satellite_constellatio...) is aiming for some data bandwidth. Though presumably at very high costs.
