Any system where support or funding for production does not depend on restricting copying: those should be inspirations for alternatives. Open-source/free software, Wikipedia, the BBC, science/academic research . . .

The internet is a communication device, and we should be using to its max. All questions about distinguishing different kinds of copying, and whether one is moral or not, do not reach the real heart of the matter. All copying (assuming good stuff) is good, ultimately, and we ought to fit our commercial system to that, not the other way around.
