But what exactly is the positive benefit to the producer that you're taking away? They say once it's out on the Internet, it's there forever and people are still sharing things made in the 70s but there's nobody collecting royalties on it. It's not like a producer can go to the courts and sue for copyright infringement either, it is essentially like a society with no copyright. Isn't it the artificial scarcity, the control of reproduction and distribution that gives it value? For the drug kingpin, ever drug user will trickle through a system of dealers into demand, the drugs can't just appear out of thin air. But another copy of the same pictures can appear out of thin air, every time it's shared around. What's the trickle-through effect? None.
Don't get me wrong, in small circles I see how producers can make money, but I don't see how driving them underground helps. Instead of one big P2P network you get hundreds or thousands of closed little circles, each producing their own material. Perhaps it's the theory that if was spread to more people, more people would get induced into doing something in real life. But for those looking to turn a profit, rarity is a help not a hindrance. It's pretty damn hard to make people pay for something you can download for free on the Internet, particularly when you know money is infinitely more traceable than bits and bytes.
It also doesn't help that parts of the US has completely lost perspective, I think the worst states are up to 10 years/count. So you could either download 10 pictures off the Internet, or you can go out and kidnap/rape/kill a kid. Either way you're spending the rest of your life in prison if you get caught, it might end up being somewhat shorter in a death penalty state but you've lost all incentive to just sit in front of your PC jacking off which is ultimately rather harmless. It's like pretending there would be no such thing as horny teenagers if Playboy didn't exist, you can take away the porn but it's not like people stop having sexual desires all the same.
