We shouldn’t tell people that it’s anonymous.
Your IP address is associated to your posts. If I were the govt, I would be running nostr relays collecting all the good stuff: eg. Who DMs whom, what you post and your IP address, etc.

Nostr is far too small for any govt to invest resources into that kind of tracking operation.
MUCH easier to force disclosure of that info from apple, google, twitter, FB, IG, tiktok, Reddit, medium and all the other centralised platforms that make up 99% of all social communications on the internet.
Just so long as it’s clear to people that nostr isn’t anonymous and that govts could track us whenever they want. I suspect that, because all messages are broadcast without encryption (like emails), they are being logged for future analysis (like Snowden revealed).
IMHO, this is nostr’s biggest flaw. We can’t have censorship resistance without privacy. I expect people will start censoring themselves as soon as someone is punished for posting something.
I believe Nostr's privacy will evolve and it will become a non-issue.
