Maybe today, but internet over radio cannot defeat physics. There is only so much bandwidth, so much space in the RF spectrum for data. But landline internet is effectively limitless. You can always lay a second, or twentieth, fiber run. A 10cm bundle of fibers can carry more bandwidth than the entire starlink network many times over, with much lower running costs.

The most effective in rural areas is generally a combination. Fiber to a central location and wifi radio out to customers. I am monitoring a property on the west coast connected via such a setup. The last relay is actually solar powered atop an island.
