How long did it take to electrify our country? How long did it take a heavily regulated monopoly to build out a nationwide PSTN? How long have ISPs realistically been deploying residential broadband infrastructure? I believe some perspective is needed for your argument.
In both cases the government and the people made it a PRIORITY to do these things. Even people in "unprofitable" areas where provided with access to both these things. If left up to big business we'd still have areas where electricity and PSTN would not be there. Trust me we are better off as a nation today because 60 years ago we spent money on giving a bunch of Farmer Brown's electricity even though it was "unprofitable" for the electric companies to do so.
That wasn't my point. My point was that even if we the people make it a priority, and we regulate/subsidize entities to deploy infrastructure that it still takes time (even longer since it isn't a priority and we aren't forcing deployments).
