You can get fiber, if you are actually willing to pay. You just aren't willing to pay for it.
What I mean is they'll sell you a fiber connection, as fast as you'd like, but you'll have to pay the full costs. You pay what it takes to have the line run and installed, and then you pay the full rate for an unmetered dedicated connection and they'll do it. Real enterprise class service with a nice SLA and all that. Thing is, that is going to run 5 figured (maybe 6) on the install and 4 figures or more for the monthly. That's what it really costs, that's what actually running dedicated fiber costs and what dedicated bandwidth costs.
What you want is CHEAP fiber. You want them to roll out a PON network on their dollar, and then sell you can your neighbours access to share that bandwidth for a low price. That's fine to want, but demanding it as if they owe you is unreasonable. Particularly since for something like that to be economically feasible everyone needs to be willing to pay, not just you. If it is a shared network, with the costs not being paid upfront, then a bunch of people need to pay, and need to do so for a fair bit of time.
If you look in to it, you'll find more than a few people that have no fucks to give about fast Internet. any modern service is "fast enough" for them. You can't convince them to spend on higher speed connections. My parents are like that. They have 12mbit cable. They can buy at least 100mbit where they live, maybe more (I haven't checked lately). They just won't. They are happy with what they have. They've used faster Internet, when they visit me they get to use mine which is 300mbit, but they don't care. To them what they have is good enough and they would rather spend the money on other things.
So if you are really willing to pay, and I mean pay the actual installation, operation, and bandwidth costs for dedicated fiber line, you can have that. However if you aren't willing to, and I can't blame you if you aren't, you can't then demand that they should give you stuff for cheap.
