There's definitely a misunderstanding, but I'm not sure where it lies.

If the domain registrant gives up their registration, for whatever reason,
and the new domain owner starts minting new URIs in the same namespace,
what implications does that have for the URIs that are now invalid (not
because they don't resolve, but because they are no longer considered valid
by the namespace owner).

As Dan pointed out, it's a low probability event that needs to be dealt
with in an out of band fashion, but it does happen.
