There's a short sci-fi story (whose name escapes me, but is mentioned in Cory Doctorow's Information Doesn't Want to be Free) in which the human race is given matter duplicators that can perfectly copy an item, including the duplicators themselves. It's basically a more fully-explored version of the "what if I can copy a car" thought, in which I think the conclusion is that creativity would flourish because less effort is put into making many of the same item. It's quite a far-reaching hypothetical, but it has strong parallels with digital rights issues.
