My friend, you yourself have been implying this whole time that Google's infrastructure is too vital and important to remove - how do you not see that this means they are too powerful? Remember trust-busting? Remember anti-monopoly activism? Nobody thought that by breaking up the railroads people wouldn't need trains anymore, but they understood the danger of allowing a single company to have such market dominance and what it that would mean for consumers. Same thing here. And yes, I'm aware this requires continual diligence as the phone companies that were once PacBell are now bigger than it was, but that lacking of failure to continue enforcing anti-trust doesn't mean the concept is wrong.
No single company should be allowed to have such influence that very idea of them going away leads to the very doomsday considerations we've been talking about. That's what this is all about.
