The types of solutions that are possible are the types they are least inclined accept. Piracy is not killable without taking away the ability to communicate privately and probably not even then. Soviet attempts merely lead to Samizdat, in spite of going to extreme lengths to track people down. Also, prior to the internet, copyright infringement was widespread over sneakernet. Attempts to control that via technical means merely taught a generation of kids how to crack software.
That's not to say there are no solutions. William Patry has a new book about copyright reform. There are new ways of doing business. For example, iTunes proved successful, in spite of the fact that anyone who wanted to could have downloaded the same songs for free. None of those things are stuff they want to hear, though. They don't want to change. They don't think they should have to change. But reality has the last word and reality has no qualms about being unfair.
