Merely using rel=license in the above example would not cause the
copyright message to be displayed to users.

Why does the license information need to be machine-readable in this
case?  (It may need to be for a different scenario, but that would be
dealt with separately.)

No.  But if a human sees a string that mentions "© copyright" or
"license" then she's likely to realize it's licencing information.  And
if it's placed next to a picture it's conventional to interpret that as
applying to a picture.  It's also conventional for such information to
be small, because it's usually not the main content the user is
interested in when choosing to view the page.

Magazines and the like have been using this convention for years,
without any need to explicitly define what indicates licensing
information, seemingly without any ambiguity or confusion.
