Sure we have. Each file is linked at least once and deleted if not.

I thought the discussion if about when a user is allowed to link / unlink
what kind of file.

And that is simple - you are not allowed to link or unlink directories. rm
is a high level command - try the low level "unlink" command and you will
see that it won't unlink any directory. And on the other hand ln won't
create links for directories. At least not on any unix I have come across.
