But if the movie wasn't worth any money to said person in the first place, then maybe it isn't such a big loss. Maybe some just do not value cinema entertainment very much even though they may watch a movie.
Absolutely. Certainly the hypothetical cameraman has no inherent right to be paid to do whatever they want to do, I only assert that the so-called utopian pirate market is incapable of sustaining cinema without drastic changes to the business.
Not to say those changes aren't currently necessary, only that if everyone chose to pirate rather than pay then all of Hollywood would likely just shut down rather than keep throwing $100+m AAA blockbusters into a financial abyss.
Hollywood shutting down would not be a huge loss to the world. Movies of cultural value could still be funded and then be made available to the public.
That's a highly debatable point. People's definitions of cultural value differ wildly, and the sort of violence and humor that many people find entertaining would be difficult to justify seeking public funding for.
