Tell that to google, they are trying to lay fiber wherever thay can. The problem isn't economics, it's willpower, why would you want to dissolve your monopoly position into a competitive one? The monopoly companies are behind the crazy regulations and terriffs, it creates a substantial impedance to competition, plain and simple. Not to mention government wanting to keep communication channels in their control for obvious reasons. One hand washes the other and the consumer gets screwed as a result.
