I saw someone bring up the "You wouldn't steal a car" argument with a Ferrari Testarossa 1984 while ignoring the obvious argument. Here's how I would compare piracy. I bought a 3D printer or a replicator. I have material to create something with it, either from recycling other matter or buying the material. I have paid for the electricity flowing in the wires to power it. I print and assemble something that looks exactly like a Ferrari Testarossa 1984.
Or how about this, I plant a vegetable garden in my back yard. The thing is, I put the seed down and water it and then it grows full size right before my eyes. This is pretty much what copying amounts to. I'm going to start calling everyone in Poland and Ireland pirates from now on for stealing potatoes from the Americas. Dirty, filthy pirateses. They stole our precious!
People buy their computer and also pay more for higher specs like hard drive storage size and CPU speed. They pay for the electricity to power their computer. They pay their ISP for bandwidth. They don't take anything away from anybody. The only way anybody would know something was happening is if they were spying.
I also have my doubts about how prevalent downloading without paying is. I believe a lot of it is people buying a defective product and then downloading the working alternative. I just read in another thread that CDProjekt stated that the DRM-free version of The Witcher 2 (the one that would have been easiest to copy) wasn't the one being torrented. The retail version was. Could be 1 million people didn't want DRM with something they paid for and so just downloaded the version without it.
Instead of providing a better business, some in the content industry would rather try to demonize people and call them pirates. Yeah, except a lot of people think that old school pirates are cool. Oops, better call them thieves. That's still not doing the job so we better call them filthy pirates and thieves. People still aren't believing that so now it's time to call them liars and cheaters too. Give me a break.
One last thing, copying and plagiarism are two different things.
