Yes it makes sense. But yy worry about this kind of thing is, how would I feel if it was a government run by Hitler/Stalin/Pinochet etc etc having this kind of extra information about everybody.

We are now living in a time when, for the first time in human history, a genuinely totalitarian government which is in a position to know everything about everybody is actually possible.

Tyrannies in the past have been called totalitarian, and they've done their damnest to keep control of everything, but they just didn't have the practical ability to really control more than a fraction of what went on. They had to depend on piecemeal stuff like informers.

That's no longer true. That means that a new totalitarianism will be able to dispense with a lot of the heavy stuff. No need to crack down on thousands or even millions to get at the dissidents, they'll be able to do it on a one-by-one targetted basis. And most people will never even know.

It's pretty frightening.
