Movie piracy (and other domains as well) is one of those, in my opinion, exceptions to the idea that “Well, if everybody pirated (or xyz’d) then where would we be?” Or something similar.
Ignoring the law for a moment, which I liken to pedestrian traffic lights in nyc, but with a wider range of consequences, the reason I usually find pirating material unobjectionable is everybody doesn’t do it (in general) and those who are of the sort to do it ought to do it, as there is “room” for their behavior.
Well what about creators? It’s an important question, but I answer that the circumstances of the consumer along with that of the creator and their product should be evaluated on a case by case basis as regards deciding whether or not to pirate.
Also it often has happened to me that piracy of some product was not the final word. That is there are a good deal of things that I went out and bought afterward anyway. Various reasons having been cause.
