You're chasing your own semantic tail here. The point that the parents are making is that copyright is an artificial subjugation of immaterial goods to behaviors and laws that naturally apply only to material goods. Ideas and expressions, by nature, entertain no notion of scarcity. Copyright is an attempt to artificially introduce scarcity and grant control to the newly rarefied goods. This process is, by nature, fraught with contrivance, and thus prone to abuse and ludicrous corner cases, such as the case where a monkey steals a guy's camera, and the guy then claims ownership of the monkey's work.
