Is a typical thing (i.e. infrastructure) that the government (federal, state and local combined) should pay and maintain ? Clearly letting private companies doing it is not working in US. Dig once, lay enough municipal fiber, and rent it to any ISP that want to reach houses/buildings. Use that opportunity to properly lay the phone, cable, and electricity, and rent them out as well to the local provider of voice, TV and electricity. And the nice bonus would be uncluttered street, no more poles and wires going from building to building. Yes, it is expensive to lay down fiber, phone, cable, electricity. But if we had done the investment 20 years ago, it would likely be ahead now, with lower cost for customers, and a thriving environment with more innovation...
