Which is great for you, but the vast majority of the world doesn't have such strong local organization consisting of members who can afford to pay for big ditch infrastructure.
I'm sorry, but in an environment where sovreignty is increasingly the dominant election issue, fiber doesn't rate.
And even if every house has fiber, there are still many cases for mobile and robust Internet that can't be covered by cellular networks.
The reality is that Starlink needs a competitor. And besides, satellite Internet from LEO satellites is a viable competitive option to fiber, based on infrastructure costs alone. It's all nice to convince slow moving bureaucracies to lay out fiber, but nobody wants to wait the five to ten years for that to happen, when you can subscribe today and get it within a week.
