Imagine you build a road. Who benefits? Drivers, obviously. But also store owners, because customers can now get to their stores. It's equally legitimate to charge the driver, via tolls, or the stores they drive to (via special tax districts). If you charge only the driver, you tap into only part of the net positive value created by the road.
This basic premise applies to cables and other infrastructure as much as it does to roads.
