I do not agree with this premises of copyright because it violate actual property right.<p>I believe that deontological ethical principles(In this case, libertarianism) override any utilitarian scheme to improve the economy.<p>However, I also found no evidence to suggest copyright and patent improve the economic wellbeing of civilizations. In fact, I feel confident enough to argue that copyright and patents harm economic progress.<p>While I am open to evidence that copyright and patent can improve the economic condition of men, but I am closed to ethical justification. Unless you can prove why copyright does not violate property rights, my opposition to copyright will  remain stern.
