So far, from what I read in your post, you haven\'t exposed any legal fallacies. However, for the sake of argument, I\'ll reply to each of your examples and show you the flaws they contain.
First off, you have your example of the jacket. The reason why you can lend it to him and no one says anything about it or complains is because the two of you can\'t wear it at the same time. Either of you is wearing it, but never at the same time. You can get technical with it supposing you replicated the jacket with the same material in the same style so the two were identical in every way, but you could be fined for that if you give them away on the street and possibly even arrested.
Then there\'s the example of the Ferrari... Anyone can drive the Ferrari, but those who do need to be insured to drive it. If they are not and that person gets in an accident, they\'re fundamentally screwed for everything they\'re worth and your car becomes useless and your insurance rates skyrocket.
Now you have the Metallica CD -- sure, you can lend it to your friends, but the point is, in the comfort of your own respective homes, the two of you are not listening to it at the same time. If you made a copy, and gave them a copy of it, then you are breaking the copyright act which is exactly the same thing as I spoke of with your jacket scenario. Why do you think copying games and distributing them is illegal or programs or OS\' or anything else that can be reproduced for free for that matter?
It\'s the same things for books as well. If I reproduced the original screenplay for Star Wars on the web, I\'d be given a cease and desist order from George Lucas in seconds and if I didn\'t, I\'d be sued and prosecuted simply because the script is reprinted in a book that can be purchased. It\'s the same thing as stealing no matter how you sugar coat it. All because it\'s easier and because everyone is doing it, doesn\'t make it right.
I’m not trying to say I’m above everyone because I have fractured an occasional law from time to time regarding this whole subject, but I’m not going to lie to myself and convince myself that what I’m doing is right by striking back at the illegal record producers or profiteering programmers or the evil Nazi practices of Microsoft.
As for iTunes, I\'m going to get it without a doubt as soon as the program comes out for Windows in the coming 3 months. I have no gumption with paying .99 for a song when the latter is paying 15.99-17.99 for a CD where only 4 songs are worth listening to.
