The cost argument is based on numbers that factor out long-term costs of letting contractors dig wherever they want. They rip the streets to shreds and since it's the lowest bidder the asphalt has to be completely redone after one or two winters. In Boston we watched this happen to most of the region during the big dig and that work was being done by the best people available.
The open access argument is absurd. What they mean is they want to run fiber down streets with high incomes and let the cable monopolies continue to gouge everyone else.
It's a real shame but if you want residential internet to get better in the US there's probably going to be a lot of federal spending involved. Which we could have managed back when all the cable lines were first being run. Back when we had a functioning government. In the 1970s.
