Kant weighs in
This Kantian perspective on the intellectual property issue is interesting. My take on the argument is that the creation of great or popular works is almost a stroke of luck and that property rights should not be strictly enforced on an intial arrangement of rights that has a large element luck.
I guess to a certain extent, I would agree: music will be made by people whether or not they are richly rewarded for it. The sheer number of starving musical artists out there is evidence supporting that. So, maybe the rights imbued by copyright should be watered down somewhat? I'm not sure, but it is an interesting argument.
