Heh. And there I went to the trouble of re-wording my post because I didn't know if you were talking about real life or throwing out a hypothetical example.
Is someone proposing a rule mandating continuous updates of contact information, the way the DMV says you have to every time you move (but nobody really does)? Or having to get ICANN's permission to go on vacation? Otherwise, you only need to exist once a year.
I'm thinking unlisted phone numbers. The phone company knows what name goes with what number, but other people can't just call Directory Assistance and ask for it.
Someone else is probably thinking: Yes, but emergency services have an override so they know who's calling 911* even if you're unlisted. And what's to stop the bad guys from getting hold of the same technology?
* Or 999 or equivalent. C'mon, work with me here.
