If you seriously wanted to pirate you can still go out and do it without a great deal of difficulty, a lot easier than you'd ever find someone willing to sell you a gun.
What about the right to protect your creations? What if you were a director, a singer, a games developer, and your big creation was just pirated because everyone had the means and will to do so. You've poured your life into it and everyone is just enjoying it for nothing, where do your rights stand there?
Don't get me wrong here, I'm probably one of the biggest pirates around. I'll make no secret of the fact I download TB's of TV and Movies a month. But the attitude that it's my right to be able to do so? That no one should do anything to stop it or try to prevent it? No, that's not right at all. The content creators need to protect their income, without it there is no income. People can go on about how they're still making money, but if there was no enforcement on sites that violated their copyright then you can be pretty much assured that more people would do it, because if they can only go after the end user then it becomes more and more difficult to actually go after anyone. People will just use VPNs, they'll claim they have open WiFi and that it wasn't them, and the cost of enforcement would be prohibitive. It's the sites providing the content that are doing the damage, it's those that should be targeted.
How about you go leave your car or house unlocked at night and then when your car or tv disappears you can just shrug and say "Well, at least I wasn't infringing on their right to free will! They were just exercising their freedom of expression!".
