Ug.. it's pointless to state how things currently work in a meta discussion about whether the current method makes sense.
I'm asking you to justify copyright, not explain it. I repeat, why do you think you should get to control what other people do with information?
> I don't think I get to control what other people do with information, but you should have the right to control what others do with your work.
And I say you shouldn't, so justify your belief. You should be able to control yourself, that's it; not the products of your labor when copied. Information is not property, you don't have less of it if I copy it and you should have no say over me copying it regardless of who produced it.
