Of course there will always be people that think "If i can get it for free, why not?" but then i have to say, a lot of people I've spoken to who torrent, torrent for one reason:
They don't want to waste their money. Imagine if a film was $5 - People wouldn't have to think "Dare i risk spending $35 on this film?" anymore, they can simply buy it, if they don't enjoy it, then they've lost nothing, whereas it's a big risk with $35, so instead of risking it, they torrent.
