I'll defer to the experts on a definition here. I'm trying to speak generally about the tax funded infrastructure versus the actual work of connecting to the backbone providers and providing satellite rack space. The infrastructure costs virtually nothing to maintain and is great for rent seeking monopolists to own and neglect while running a city scale network connected to the backbone requires constant maintenance and upgrades to keep up with demand and the dynamic security landscape.

I guess my argument is Comcast shouldn't be they only competition for coaxial internet if they can't offer an internet only service, without discounts, for less than their cheapest regular rate off contract package.
