I agree.
I think the more powerful the technology is, the broader the scope, the more you have to be careful and the more privacy protections and considerations you need. That's what proportionality is. You have this more intrusive tool, so you need to have a more rigorous protection mechanism.
I agree with you. The human element is important. We're talking about privacy as a principle. It's a fundamental right, absolutely, but it means that, at the human level, we're all less free if we lose our privacy, if we're living a life where we feel that we're constantly under the microscope and that people can see what we're doing, where we're doing it, what we're buying....
I point to one of the earliest articles on privacy called “The Right to Privacy”. They gave the example in the 1800s of someone who was collecting rocks and said that privacy means you're allowed to do that and not everyone in the village gets to know which rocks you're buying. That's your information.
Today, obviously, we can see that it's even more powerful. This is part of our freedom and our individuality, so we need to make sure that reflex.... It's not to say that you can't use technology—you can—but we have to do this bearing in mind privacy.
