I sense that people are getting too personally invested in defending piracy, lest it reflect poorly on them. For the record, I have pirated media in the past. I consider myself having stolen something, and hold myself accountable for that. I'm all for a revision of the way our economic system values creation and creators, but that's another discussion; why one commits acts of piracy is completely independent from whether or not, by the definitions used within the present system, they stole a product from a creator.
What happened to creating for the sake of creation? Solifuge, you seem to have thrown that possibility away from the outset.
People who create for the sake of creation don't generally ask for compensation. If they do expect something in return, and their creation was taken or experienced without this being given, it's definitely still a violation of the social contract by which the creator allowed their creation to be owned or experienced by others. If they ask for nothing and nothing is given, the contract is upheld.
Satisfaction is not an innate guarantee of out economic system; when you go to the supermarket and buy tomatoes, it's your responsibility as a buyer to determine whether the tomatoes you buy are fresh or not. Just the same, it's up to the consumer to put enough research and forethought into purchasing a music album or game before buying it; the creator does not owe you once you purchase something, no matter how much it failed to amuse or entertain you, since you've already "consumed" and experienced the product.
Replace piracy justified by the "I wouldn't have bought it anyway, because I don't know if I'll enjoy it" argument with a grocery patron who wouldn't buy a Cantaloupe because they were unsure if they would like them. Rather than seeking out a sample of a Cantaloupe from a friend, the person steals a Cantaloupe, so they can taste it and decide if they'd have bought it or not. The same works for media; rather than doing the research on a product, or trying a demonstration out, if they steal the product they still consume it without offering anything in exchange.
Our system isn't one that allows consumers to place a lower value on a product, if the producer asks for more. It's up to the consumer to convince the producer to lower that price to something they would find acceptable, and the producer to decide if they can afford to offer it to them for that price.
