Completely incorrect. People collect pirated movies, TV and music because they can. However, there is no evidence whatsoever that they would have otherwise paid for that content.
As a personal example, when I was in college in the 1980's, I had a ton of cracked Mac games and software that was freely passed around the dorms. I would have NEVER paid for any of it - not one penny.
Currently, I know people who have huge illegal movie, TV and music collections that they do not ever (or very rarely) watch or listen to - they just collect them. They would never pay for them and certainly would not pay for a movie ticket if they were not otherwise available.
On a related note, it has been shown time and time again that if something is provided with easy access and at a reasonable price, people will pay for it. If not, people will find a way to get it otherwise. The content providers need to get this through their heads.
