The truth is that most places in the US have multiple layers of local and state levels of bureaucracy that make it extremely difficult for anyone who has not paid the "franchise fees" to string fiber. Even wireless is difficult since you need fiber to cell sites and all the same hurdles make it ridiculously expensive to get fiber to the towers. This is a problem that it almost impossible to solve on a large level since it is all controlled by municipalities and state puc's. This is why most people will never see GF or similar cheap Broadband in this country for a long time if ever.
