One might have nothing to hide from one's neighbor either, but one might wonder why he is keeping a detailed log of one's comings and goings, visitors, the times the bathroom light is turned on etc, as well as attaching tracking devices to one's car, bike, skis, and even clothing. One might get really uneasy if one finds out he has been collecting detailed information about one from the grocery store, gas station, movie theater, and restaurants etc. Even if one is not doing anything wrong, one might feel uneasy about having a "permanent record" of all one's movements tied to one's full biometric information.
