How is it a permission system? It's a way to prove your identity safely, online. No proposal/implementation that I'm aware of (maybe outside of China, but I'm not familiar enough) that actually conditionally does so based on preconditions and blocks you from actions. It would probably be actively illegal to do so in multiple countries.

I mean, that's not true. LexisNexis is the company many car vendors send your driving data to, to be bought by insurance companies to do adaptive pricing. Banks don't necessarily need that data, but if they did, they could buy it too.

Which is why it's better if it's the government - there can be laws, regulations, pressure, judicial reviews to ensure that only legitimate uses are fine, and no such discrimination is legal. Take a look at credit scores in the US - they're run by private for profit companies, sold to whoever wants them, so credit scores have become a genuine barrier to employment, housing, etc. If this were managed by a state entity (like in France, Banque de France stores all loan data, and when someone wants to give you a loan, they check with them what your current debts are, and if you have defaulted on any recently; that's the only data they can get and use), there could be strong controls on who accesses the data and uses it for what.
