Ask HN: How to Get Fiber Installed

The only ISP we have is Cox, and they only offer Copper Cable with low speeds. I've tried filing FCC availability complaints, but they were fruitless to get Cox to install Fiber at our neighborhood. I've also attempted to do the same for ATT and another local ISP who offers Fiber within 1 mile of us without success.

Is there anything else I can try to get fiber at our house? I read about a person setting up their own ISP due to lack of Fiber accessibility, but I AFAIK there isn't government grants offering the same incentives that Michigan does. I live in Louisiana, Baton Rouge area. I've tried the T-Mobile 5G wireless internet, but the speeds are insufficient to stream 4k connect even with a cat 6 wired connection.
