It's not just law enforcement though. With the way the laws are today, you could have the trusted entity selling that data if they're partnered with some consumers. If you save the cert usage (on the consumer side) you could eventually utilize it if the trusted entity changes hands, policies change, etc. The government is also a potential malicious actor depending on which government and how you want to define malicious.

Of course there are other issues in the chain concerning anonymity, like ISPs.
