“Security by obscurity” is very much an end user “i don’t need to harden my server/accounts because nobody would bother hacking me” attitude and is really is “dumb as fuck”
But KYC is just expanded due diligence before providing services, thats why I thought it as privacy issue as to why someone would be against it as opposed to it security wise.
I still don’t see how you’ve gotten from that to “nationally enforced security by obscurity” though
