This is a specious argument. It is impossible for us to gesture at the works of art that do not exist because of draconian copyright. Humans have been remixing each others' works for millions of years, and the artificial restriction on derivative work is actively destroying our collective culture.

People have an incredible desire both to create and to enjoy the creations of others, and that's not going to stop. It is very likely that the concept of the $1B movie would disappear, and in trade we'd get the creation of far far more works.
