Yeah, but infrastructure is still required.  In some cases, the power company has to run fiber to the neighborhood. In others, they use the MV lines, but have to put digital repeaters about every 2000 feet on the line.  In others, they use 802.11 to get to the house.

The premise that the infrastructure already exists is flawed.
