coverage to an entire area is either via "small number of satellites" in geostationary orbits or massive amounts of satellites for low earth orbits, you cannot have both.
"Just replaced by another" is massively oversimplifying every aspect of this, not just the act of putting an object in orbit, but also the coordination of that many MOVING satellites, their fuel levels / end-of-life procedures, all the ground infrastructure needed to support it, and the total amount of energy that this system requires (both on the side of the service providers and users).
Connecting rural or places without internet is not a technical problem, like everything in the world we built it is an issue of priorities. Starlink was not created "for the good of the farmer".
