If you never intend to make your URI dereferenceable then there
certainly is no point in making it an http URI.  You might as well use a
non-dereferenceable URN.

However, the purpose of this discussion is to come up with community
recommendations on minting URIs.  As such:

 - They will be recommendations, not requirements.

 - They should be designed to best benefit the community as a whole.

It seems clear that any such recommendations should be designed to best
facilitate the publication and re-use of URIs by others, and making URIs
dereferenceable to useful metadata is certainly one convenient way to
help do so.

In short, I think your example has nicely illustrated the fact that a
particular URI owner could still have good (or bad) reasons *not* to
make its URIs dereferenceable, and hence may choose to use URNs.  That
is its prerogative.  But that does not mean that our *recommendations*
should encourage such practice.
