Somehow we managed to get power and POTS lines to pretty much everybody. Hell, the 2700 foot mountain peak behind my house has power run to it. This bullshit that we can't run fiber or some other networking to every house.

It's not that it's economically infeasible. It's that it's just not as profitable for the ISPs as running a smaller, closer network in a populated area. So they won't do it. Why would they care about covering a huge area that doesn't make as much money? All they care about is money over all else.
