If the community can't afford Starlink, surely they can run Fiber and buy equipment from Ciena and Nokia (Huawei outside the US) to light it up themselves since it's more affordable than Starlink in your view.
That is not the point. These communities depend on their state for their infrastructure, the state was (hopefully) able to provide them with garbage disposal, sewage, electricity, running and clean drinking water. The state should also provide them with quality telecommunication infrastructure.
