The law of supply and demand. The answer is not, "Well, look for it in digital form on a torrent site."
But you know that will be (and already is) precisely the answer for the majority of people. The digital supply is infinite, so the law of supply and demand dictates that the cost must be zero. I make no statement about whether this is morally correct or not. It's simply the way it is now. Anyone born in the last decade won't take even two seconds to ponder the ethics of it. Music, films, anything that can be rendered digitally is now, and forever after, simply assumed to be free*.
You can get into a red-fanged rage about the unfairness of this fact, but it
is a cold hard fact, and sooner or later those parts of the world that haven't already caught up will have to adjust to this new reality.
