Copyright is a red herring. What we want is to encourage creation of valuable information products and services. Historically, copyright was one way of doing that, because copying information directly was difficult and required apparatus and physical tokens that could be policed relatively easily. When copying becomes as simple and trivial as breathing, policing the act of copying becomes intrusive and laborious.
So different mechanisms of encouraging content creation need to be found; the fight we should be fighting has little to do with preserving copyright in its historical form.
All of the major historical changes of worth in terms of law and procedure all arose from doing things that were socially judged wrong but in hindsight we see they were right.
I feel copyright is one of those. I want to see the individuals that make the creative digital goods I consume well compensated and happy, because they make amazing things. But simultaneously, I realize my duplication of that good costs no one anything except potential lost sales and fractions of a cent of electricity.
