Why care about copyright anyway? It’s a dry topic, but in a world of mass media and computers it’s an absolutely fundamental issue.
Should it exist at all? Is property theft in this case, because there’s something wrong with the notion that you can own an idea? Should it only last for 5 years? Would the world be better if it didn’t apply to sounds and images, because that would be the end of the mass culture industry? If there were only patent and not copyright, because that would take the money out of intellectual life? (Taking the money out of politics is supposed to be a good thing, so why not intellectual life too?)
