PBS's _spying on the homefront_ piece from 2007 already described this very kind of omniscient private database.

The government itself isn't constitutionally allowed to build or run anything of the kind, but it can commission friends in the private sector to do one and query it with little to no oversight

I am definitely not uploading my face and ID on Discord or any site

A purchase works as follows: I like ice cream. I give you 5$. You give me an ice cream. I enjoy ice cream.

This is: government likes private health data. Hospital gives Palantir 5$, and your health data, repeat for 1 million patients. Palantir gives the health data to government, employs the nephew of the head of the healthcare regulator. Your unemployment gets denied because the doctor said you could work.

Buying means exchanging money for goods and services. This is exchanging money AND goods AND services for nothing. It's highly illegal for private companies, if you try it you'll get sued by the tax office the second they see it and find all company accounts blocked "just in case", but of course if you are the government, directly or indirectly, it's just fine and peachy.

And you might think "this makes no sense". But you'd be advised to check out who appoints the head of the hospital first. It does make sense. (In fact just about the only break on this behavior in most EU countries is that the Vatican still has control over the board of a very surprising number of hospitals. Needless to say, the EU governments really hate that, but there tend to be deals around this. For example, in Belgium the hospitals get 50% less per resident. These sorts of deals were made, but they now mean that if the government wants the Vatican out of the board ... they have to increase spending on that hospital, often by a lot. I'd call them "Vatican hospitals" but one thing government and the Vatican really agree on is that they do not want patients to know the underlying financial arrangements around hospitals, and in many cases it's quite difficult to find who controls a hospital even though it's technically public information)
