Most people use the internet for entertainment, people can survive watching Netflix at 1080p/720p, it isn't debilitating. If I'm wrong in my assessment, give me use cases where you require fast internet in a rural area.
If the question is cost, I don't see how laying fiber and equipment for hundreds, if not, thousands of miles is a solution to reducing cost (unless it's subsidized by the government).
Spending billions on mostly "entertainment" is a waste.
