I disagree. I believe that the good of society should be paramount. It is in the interests of society to have as much access to IP as possible as this allows learning and dissemination of cultural heritage. It is, however, also in society's interests for peple to create new IP and they will only do so if they are properly renumerated for that IP. Fundamentally there is thus a balance of interests which society is at the heart of. To limit down the purpose of copyright law to allowing rights holders to make as much money as humanly possible from their creations is, IMHO, not looking at the full picture.Despite whatever impact there might be industry-wise, surely when it comes down to the rights and wrongs of copyright the individual, the actual copyright-holder's rights should be paramount?
Libraries are a good example of something that, at first glance is not in the interest of the rights holder (you could claim that otherwise people would buy the books instead of borrowing them from the library), but that undoubtedly have a net positive to society.
