Rather, you forgot that *every* entry that references a file is a hard
link.

To ask for a filesystem entry referencing the file contents *is* to ask
for a hard link; and there can be zero or more of those. The case where
there is exactly one of those for a given file is the special case, and
should not be assumed.
