You still had to build-out the last mile though, and thats what will get you. You either need private easements, or be a registered telecom utility to use public utility easements. That last mile is $20k +/-, depending on your circumstances. If your semi-rural or less, there's ROI sucks. Hence, many smaller ISPs are wireless.
At least in area, there are already a number of wISPs, 5G is rolling out, Starlink eventually. and lots of gov't funding going to the big players to expand their networks (and drive the start-ups out of business.)
There some other business models out there too that look interesting. Underline in Co Springs, for example. They provide a basic tier of service, in order to qualify as a telecom, install the fiber and then allow multiple competing ISPs to use their network.
IMHO, any utility that has the benefit of government privilege should be required to allow competors to use the infrastructure that the taxpayers funded.
I'm waiting on one of you brilliant folks to defy the laws of physics to create a decentralized, wireless mesh internet.
Basically everyone out there (including me) is on starlink now. Turns out the subsidies were not only inefficient, but pretty pointless.
These guys have dark fiber right in front of my neighborhood. They service cell sites for Dish Network near me as well. It's interesting to look through their services. For example, you can get fiber service with layer 2, where you're responsible for adding your IP stack over top of it. Or you can buy at layer 3, where Segra is already running a stack, and establish mesh connectivity. So if a fiber is cut, you'll get another working path. Build your network over the top.
Pretty interesting to understand what's available.
