Psudonymous systems were when we started creating an ID on the server side .. that was an improvement because original anonymous internet was incapable of keeping a history .. 

The key pair systems particularly that are implemented on client side .. and thus KYC free  ..are the best (physically possible) implementation of anonymity... So I call them "near anonymous" systems 

The problem is NOT the system .. the problem is people attach their real IDs to #nostr IDs because they want to leverage  their pre-existing networks  .. 

If you want to popular .. you can't have privacy ..people will find out everything about you no matter what you do ..
