Satellites that have to communicate with a ground station, unless they want to do all the traffic in a region over the laser links, but those links will have their own limitations.
I’m not sure what the ground infrastructure is specifically, is it spacex hardware that connects to local ISP stuff or is it their own ground based infrastructure. That ground infrastructure is usually what part of getting approved in a country involves. Doing only laser links for a whole country would be too much. (Edit: I mean it’d technically be doable, but it’d greatly reduce their network bandwidth vs having a closer ground station, so fewer users and lower speeds)
The other option would be a hybrid situation where starlink backhauls one of our telecos internet but the local infrastructure is built and owned by them. In the future you could then backhaul with another satellite network in theory. Basically drop a 4g/5g tower in the middle of nowhere and connect it to Starlink.
Starlink offers the low latency that others can’t provide which is needed for more real time applications and at a much more affordable rate. Maybe in the future there will be another (edit: low latency) network that rural people can rely on, but that isn’t today, or tomorrow, or next year, or the year after.
