Sounds like all you’re saying is Europe doesn’t respect personal privacy or the right to go about your life not being harassed by government officials when you’ve done nothing wrong.
I’m saying that yes, and also that you can’t benefit from certain things like tax breaks, pensions and proper healthcare without identifying people.
In the case of US gov., they’ve been caught repeatedly selling taxpayer info for money. THAT is the problem.
Yes, this is a problem but I don’t think that you can fix it by making it harder to identify people… Because that also increases identity theft, general criminal behavior, make you unable exert other rights etc.
