The prioritization is to prioritize. The law was meant for authors, and you should still put the authors at the centre of the law, because everybody has invited themselves into the copyright law, all kinds of users, specific users and so on. It's not really a copyright law anymore; it's a party to which everybody is allowed to go. I would go back to a copyright law where the author is at the centre of it.
I'm not saying you don't have to have exceptions, but you have to say that it allows the authors to be at the centre. That would mean either that the author authorizes uses or that he is compensated if he can't authorize.
If you have that, you have a framework that respects the author. He authorizes, so he says yes or no; or, with the private copying regime, he doesn't have the right to authorize and the public can have access, but we put a mechanism where he gets remuneration.
