I worked at a GEO company. They have a HUGE department just to work with governments to buy or keep their spectrum. The rules and regulations for spectrum are insane, and not just build this cable here in my county/state/country, but now this beam goes across borders what do I do? Oh wait, this region is contested by China/India we have to sell differently to each government.
Cost of labor => It's a calculation of how many people can be served per 1 mile (any unit) of cable. If that number is 20, cable wins. If it's 5, hotspot may win (which also uses cable FWIW). If it's 0.5 then these new satellites win. 5G may try to take more market from ISPs but they know they'll have to innovate to keep customers. I can 100% see cell towers being cheaper than cable, but not in every situation.
It's about supplementing not replacing infrastructure.
