Sort of?

If you're going to provide wired service in rural areas at all, doing it with fast fiber isn't a significantly different maintenance cost than using the old stuff, but it has a high one time cost to transition from copper to fiber. The cost of doing that is more like per-mile than per-customer, which makes the per-customer cost a lot higher where there are fewer customers per mile. There are areas rural enough that nobody would spend the money to run fiber even if there were no regulations at all.

Whereas for NYC it's just unambiguously corruption and regulation destroying competition.
