I think something similar was dicussed here on forum in the past. Part of the suggestions was to have something like that in decentralized form, especially with things that are fairly cheap and uniform like internet balloons that many people can afford and launch together across the world. It's never a good idea to depend on centralized internet/satellites for decentralized networks. The communities should moving to full decentralization and not jumping from one centralized internet to another centralized internet.
That sort thing can be crowdfunded by decentralized-tech enthusiasts around the world as one of the few ways to have  decentralized internet in isolated communities
