There's a little unspoken benefit about what a true, affordable, universal-coverage broadband system could provide for: drones. Envision drones that can provide high quality real-time streaming (commands to the drone, imagery back) without requiring line of sight or effective cellular service.
Individuals and companies could get the sort of drone communication that today only exists for militaries. Buoyant drones (hydrogen, helium) could stay aloft for long periods and go anywhere. Conceivably a hydrogen-powered drone could stay aloft until its electronics failed, via condensing atmospheric moisture via a hygroscopic material and electrolysing it to replace the slow rate of leakage (using solar power). So picture a world where, say, anyone could buy a mass-produced mini spy drone and send anywhere, even a war zone with no infrastructure, and have it fly at a height where it would be almost impossible to spot. It would in most cases cost significantly more to take down than it costs to build (barring "drone killer" drones, but then you get to needing to maintain a large distributed inventory of them and a sensitive nationwide detection system that works at all altitudes, and you're just inviting people to come up with countermeasures). It would make it increasingly difficult to lie about human rights abuses, war crimes, armed incursions, etc.
I once looked into what it would take to make such a drone previously but quickly realized that the bandwidth costs alone via today's satellite internet services would get pretty astronomical quite fast, turning a "cheap drone" into a prohibitively expensive one. But this could change the picture. If satellite internet is cheap and widespread, not only will your bandwidth be cheap, but it also means that your connectivity hardware will also be widespread and cheap.
On the home front, one of the big concerns by regulatory bodies for all of these drone-based services companies are eager to launch is of course loss of connectivity - which is one reason why, for example, the FAA has been resisting them in the US. But if satellite service to a drone is much less likely to suffer from the reception irregularty that plagues cell phone towers. And you always have cell phone connectivity as a backup. You're greatly improving the overall reliability of your drone communications, which should make it easier to start getting commercial drone services approved by regulators.
