We all – not just those who go to the movies, but everyone – also pay a hidden cost: The cost of the copyright system itself. You imply that this cost is necessary for “high-scale, ambitious entertainment”, but I say that you should then be held to pay for it, instead of society as a whole.
It may or may not be true that “high-scale, ambitious entertainment” is unsupportable without copyright. If it turns out to be not supportable, it would be like the pyramids: Large, impressive, and expensive things which the structure of our society and our economy can no longer support the constructions of. I.e. the society we live in could concievably be re-organized to again support the construction of pyramids, but we choose not to do that, in order to have a modern society and economy instead.
