Of course it is required in Europe. Where it is not required, you are already known. For example, if you live in Berlin you have no possible hope of getting to Brussels to attend a protest without every movement you make being put into a database.

In America, we do still have one method of transportation which is not entirely watched - if your car doesn't broadcast its GPS location. Of course there are cameras everywhere, but it is possible to visit a lover or a brothel or whatever without being tracked and blackmailed if you take proper precautions. You? You have no hope. Don't ever think about meeting a lover if you want to run for office one day.

The only people who can run for office in a state with no privacy are the people with access to erase their data from the database.

But of course, we should give up this one method of obfuscation of our movement -- because we might be speeding in the car. If we did so we would be in a complete prison.
