Let me introduce you to SCHUFA[0], a credit scoring system in Germany. It has livelihood implications that make it very hard to live without a good score. Good luck finding a flat with a bad one.

It doesn't blur the line between private and public but again, it's a slippery slope. The tracking and scoring infrastructure is there, it just takes will to steer it to another direction.
