Privacy laws IMO have multiple purposes, only one of which is protecting the citizen’ right to their own data.
Another big one is balance of power. If a entity — be it a state, company, individual or a group of indivdiuals — knows everything about you, they thereby create a asymmetry of powers they can leverage for their own interest. In addition to protecting the individual, privacy laws are also meant to reduce or limit that kind of asymmetry to avoid the social consequences that might be linked to it.
Not without a reason it is Germany which has one of the strongest privacy movements in the world, because many of them know first hand, what data in the hand of fascist and communist governments can do to the life of individuals.
When the Nazis marched into the Netherlands, the having the religious orientation in a central database was was made the difference to many lifes. And that is, what makes data different than somebody’s knowledge in their heads: if the Nazis march into your nation you could take the decision whether to tell on your jewish neighbour or not, while in the case of real data you can’t.
