Communication Ethics book part for The Concrete Part/Human Perception Model. (This is an automatically generated summary to avoid having huge posts on this page. Click through to read this post.)

Copyright law, as mentioned before, is built around a model where expression is the root unit of communication. To build a system for the future, we must create some other model that models communication... and the more-complete communication model described earlier can again guide us.

In light of that model, it's fairly easy to break things down into two parts: the concrete part(s), and the human-received message. While they are very strongly related to each other, they are not the same thing and you must understand them both separately before their interactions can be understood.
