This is pretty naive. What happens when you develop and extend such a system in a way that it can track who you interact with? What about social credit scores? You might go out to a social event with a very distinguished social credit score of 820 and get knocked down to 69 just because you were in proximity to Bob and Alice, who happen to be on some blacklists for their work in cryptography.

What you're staring at is the gateway tech that brings in a dystopian society. At first stuff like this is fairly benign, but slowly over time it ramps up into truly awful outcomes.
