Every is a bit of an overstatement. Generators in some places are a thing. (And so are fairly large areas without houses.) But generally, yes, also subject to the caveats in another comment.
Satellite broadband does seem to be the "hack" for making locations that don't have broadband or really usable cell coverage in many cases practical.
Sorry but it's not satellite broadband, it's the same rural electrification that is the "hack".
My electric cooperative rolled out fiber to every address in the 3-county region it covers. It did so within a year. How? They already run poles everywhere, so they asked "why should we bury fiber?" As it turns out, it's easier to scale out on the pole!
