Or we could acknowledge that cable infrastructure was highly subsidized by taxpayer dollars at all levels of government (federal to local), such that whatever risk or cost the cable companies themselves did "invest" has been more than reimbursed. Furthermore, we could recognize that the function of the Internet is now much closer to city sewage (you *can* still use an outhouse... but do you want to?) than to satellite TV.
As such, especially given how many of our tax dollars were sunk into building it, we could decide that, by eminent domain, the cable infrastructure becomes public property (with the cable companies being "properly reimbursed" at rates analogous to those at which individuals get reimbursed when the gov't decides it needs their land), and Google or maybe even a bunch of new local "MomNpop ISP" companies can starting using the EXISTING lines to the home that we already paid for to provide up to 10Gbps symmetrical over full duplex DOCSIS 3.1.
But, you know, our current Congress or FCC wouldn't want to have a free market or anything...
