Because we've been fighting off having conditions imposed on us for generations now. The us government tried to enforce conditions on the drinking of alcohol a while back. Didn't go so well. Imposing restrictions in this regard has never worked. People have been trading copies for a very long time now. Hell, the BBC is calling for people to hand over their tapes of early doctor who episodes cos they have lost the originals, and those who have them are still wary of handing them over cos it goes against the very idea of why they made the copies in the first place. You'll also find that most pirates are spending way above the norm for media they love. Myself, I pirate a shit load of music. My biggest expense after rent is music, 90% of that going to digital and physical copies (I'd love to spend more on gigs but I can only to go to so many in a week). I literally spend more on it than I do on food and utilities.

Sorry, but content creators should decide by themselves how to sell their goods.

and i should decide for myself if i want to buy it.
