Tiggerkim , that argument is facetious , downloading a new copy of the dvd does not make the seller lose a copy of the dvd like they would lose a chair, they may lose a sale but that is completely different
WRONG!!! It is exactly the same. How does the seller make his living? Buy selling DVDs, if you copy it you are a thief just like if someone stole your DVD that you bought.
I want to agree with you, but I can't. He didn't lose a physical item, just a reference to information he had already learned by purchasing it. The fact that he already owned it does not cost the seller anything because a purchase is not being circumnavigated - it already occurred. I don't believe you can put a price on knowledge twice; now THAT would be unethical
What would have been the difference if he had copied all his DVD's on portable hard drive in case of an emergency like this? Nothing - he'd plug it in to his new computer and replace the files. Voila, he just committed the same "heinous" act of downloading his lost DVD's
As for losing his books, there is no physical replacement of his books online. You can download the text but it will NEVER replace the value of the physical text in your hands. It is not unethical to download those either if you already purchased them, but I would not bother, personally. It isn't a matter of ethical concerns, but pragmatic ones. I like the idea of having the book in my hands and turning the page with my fingers (and the smell of the book), rather than clicking a button or swiping my hand over a touchpad
Losing the gimmicks is self explanatory though. You can make your own, but there is nothing better than buying high quality stuff that can't be replicated at home
