Can you phrase your thought as a causal chain so that I don’t have to guess what you mean?
After the German occupation in 1940, the Nazis accessed and exploited the Dutch population registry, including religious affiliation.
About 75–80% of the ~140,000 Jews in the Netherlands were killed.
This is the highest percentage in Western Europe.
Compare that to France, which had a more fragmented administrative system, and less complete central records and 25% of Jews in France were deported and killed — a much lower percentage than the Netherlands.
As usual, when reaching the Godwin point, the idea is not for you to take it at face value, but to extrapolate to your situation.
The concentration of power and centralized people tracking are eventually always abused, and once your system becomes less free (which has historically eventually happened on a long enough timescale), you will pay the price for it.
In our case, having a full history of all opinions, interactions, locations, and behavior linked to full identity of people is what we are ultimately talking about here. It's already well on its way, but it will make it worse.
The more you concentrate power and feed data about people, the greater the potential damage.
And of course, it doesn't need to be a full-on dictatorship to get problems with those.
It's a spectrum of increasing problems you will get, the more you lean into it.
Sorry, but why would the Dutch government need to know all those details in the first place? Did Dutch citizens never ask that question back then? Nazis or no Nazis, that was an issue waiting to happen. I guess it wouldn't have mattered if they did, since the Netherlands was a kingdom and people didn't have much say into how the monarchy ran things.
Maybe the Dutch citizens did ask these questions you think they did not ask, but the Government won.
And the current legal setup mean you would have to own a google account, a terrible private life setup.
So that is why the government needed to know how many Catholics or Jews there were.
Well, not really. Age verification doesn't have to, and IMO should not, lead to a linked identity. Just a blind check "are you a real human older than X years old? Yes! OK". That way you get the benefits of age restrictions and real human validation, without any of the potential privacy ramifications.
But to be clear, most real people's online presence is under their own names (or linked trivially to their own names, like a cutesy turn on their name for an instagram handle that is linked to their Facebook account which has their full name). It's already possible, and done, to track your public social media presence and interactions. Places like HN and even Reddit are much more niche than that.
It should not.
That's not required though. Your friends have already given your name to them by allowing the app access to their contacts.
Not to detract from the rest of your message, but it wasn't centralized; the data was collected and stored in each municipality separately. The only part that is centralized is the historical archive: after death, each person's info card is moved to the National Archives.
This system has never been centralized, even after digitization: birth records are still kept only in the town of birth, and when moving house your active records must be officially requested and the transfer manually authorized between municipal systems.
