Yes everything you've said about the possibilities is technically true, but it hasn't happened and there is no evidence it will happen. The RDOF has awarded another provider funding to bring fiber to within a few miles of my place but not directly to me.
Meanwhile I've been on Starlink since last February. I just checked and I'm getting 110M/12M with a 28ms ping time, which is 10x what I was getting for effectively the same price. Not only that, if I want to go on the road I can pack that little dish and take that bandwidth with me just about anywhere in the US. If I was broke I could pool funds with a few neighbors and we could split the cost.
With that available now, why would anyone spend millions of dollars to drop in a 5G tower to pick up another 50-100 customers?

Your county would—and should—spend a few million dollars with some extra funding from your state and local telecom companies to drop a few 5G towers to pick up a few thousand more customers and voter happiness for sure. Your county counsel can call it something like Rural Broadband initiative and have a plan to bring a broadband connection to 30-70% of under-served rural households in the county before 2030. A good politician should be able to sell it even to city folks as serving the community.
It's a utility. If it costs twice as much as elsewhere you still need to pay it, until it starts getting really difficult.
Serving these communities with traditional infrastructure and maybe a 5G tower is very possible today, and frankly not that expensive for a country like USA. I think you undercount the political feasibility a bit. Politicians in the USA make a huge buzz about serving rural communities, infrastructure is a political buzzword at the moment. A good politician could easily capitalize on rural broadband. They don’t even have to be that well intentioned since they could take some lobby money from the telecom companies and bid out the infrastructure build out with conveniently specific requirements for contractors their family just so happens to own stock in.
