You seem to have misunderstood the point. The German summary that linked me to this study shows that only four datapoints in your past months' and years' record of movement tracking are sufficient to identify your person as if you would have given a fingerprint.

The Israelis are about building psychological profiles of your character on basis of your movement record. They - at least claimed - to be able to even predict by your data whether you are or become a terrorist or not.

Google, Facebook and the like establish not only consumer histories but either they or their customers - companies - establish psychological profiles as well. Obviously you can do much more with such data than just personalising advertisment. An employer for example can ask such a profile of a candidate whether he would be a reliable, solid worker, or not. Insurers could ask whether you are a personality that tends to take risks (health and sports), or not.

And since all this stuff is recorded on US servers and is object of American laws, it is stored for virtually forever. That means if you ever, in the future, become effected by for example a crime case and you are under suspicion, data from 15 years ago could be used to investigate against you or maybe even form a case against you.

Movement profiling is NOT the casino security knowing where you are inside the building, and checking you on monitors. It is identification, and character profiling through your movement behavior.

Companies and governments will - and already do - abuse these data, no doubt. The possibilities from this are terrifying. We could as well chip newborn babies and add behavior altering drugs into the sweet water supply system.
