you should either contact the ISPs that offer that type of service and see if they will provide service in your area, or you could bring the matter up with your local government.
I live in the Metro Detroit area but out on the fringe, still in farmland. We don't even get barely adequate cell phone service. Lot's of no service areas. It really fries me to see films of residents of 5th world countries wandering around in the rice paddies with their electronic gadgets.
10 years ago, after fighting with Verizon for years over landline internet capability, we finally got it with an expensive LAN landline modem. We got 50Kbps. Wow. That lasted for a year, and then a thunderstorm took out the telephone in Monroe for 5 days. When it came back, the modem wouldn't connect at better than about 20Kps, but the actual throughput was more like 200bps. We fought with Verizon for a year with no success. Comcast ends at the next house to us across the road. After 4 months of trying, I could not get Comcast to come and give an installation quote. That is how we ended up with DirecPC. My first year with DirecPC was not so good, because they sent a marginal power supply that resulted in my unit providing only 10% of what it should.

With a 20Mbps connection vs a 50Kbps connection, one can download 400 times more data in the same time period.
There didn't used to be the availability of downloading a movie. Webpages didn't stream unwanted video advertisements. You didn't download 3GB to upgrade to Windows 10. 3GB on a 56K modem takes 480000 seconds or 5.6 days, and the chances of failing were about 100%. You didn't have a bunch of smartphones and tablets on one WiFi account.
I fail to see the logic that placing a data cap improves economic greed if system bandwidth was not in the equation.
