The copyright to the derivative work, once created, belongs to its
creator, not to you. Thus it makes no sense for you to be able to
directly restrict the distribution of those derivative works.

Exactly.

Arguably,
you can make such a restriction as a condition of a license of the
ability to create one, so this entire discussion is splitting hairs.

No, no, no! Supppose you create a derivative work in the course of
normal use.

But if you allow the
creation of a derivative work you can NOT, under copyright law, restrict
its distribution.

Alas, it's not that simple. For example, suppose you buy a copy of a
music CD. You decide to add some extra drum sounds to the work. Assume, for
the sake of argument, this is deemed to be fair use. It would be totally
unreasonable to argue that you can now sell copies of this derivative work,
simply because you created it legally.

We are getting far afield here and into very technical waters. However,
no court has ever held that a lawfully-created derivative work may not be
distributed to licensees of the original work with the permission of the
creator of the derivative work in the absence of an agreement. And that's
what's important in the GPL case, because everyone may use the original
work.
