The public disregards copyright law because it is out of sync with the digital age. We want the right to resell digital content (ebooks, etc.) that we've paid for. We need transparency in the marketplace to understand what rights we have.
Additionally, as responsible creators we need to be able to freely remix existing music and other forms of creative expression to create new works without undue fear of prosecution. This upholds the original Constitutional purpose of copyright, which is to promote progress.
This will nurture the process of innovation and the sharing of our culture. The language of the existing copyright law must be changed to accommodate the way information is being created and consumed in our digital world.
