That's what they do here in Utah: UTOPIA (the municipality) runs its own fiber lines, and leases its network to private ISPs. That way, there is a single physical network with competitive pricing. Of course, that doesn't stop Comcast, Centurylink, Google Fiber, etc. from running their own networks, and UTOPIA's coverage generally doesn't overlap where these other ISPs already have infrastructure.
