Sounds like a nice distinction on the surface, but just to continue to
play devils advocate for the moment; can you give me an example of an
abstraction that would make sense without some concrete instance
existing for reference purposes? I'm pretty skeptical that any such
pure, "unattached" abstraction -- which would be the ultimate
extension of your proposition -- is possible....
