Are you an idiot? Yes, that's the way the current, dying system works. It's hard to be a gatekeeper when there are no longer any walls. The middle men are are no longer needed. Tough. This is an exciting time to be a musician though!
It's seems pretty clear that I:8:8 is setting up the limited monopoly. Yes, it is an infringement of individuals' natural rights, though its intent is to benefit society. Jefferson's quote seems to explain why the authors of the constitution thought this was a good idea.
"Inventions then cannot, in nature, be a subject of property. Society may give an exclusive right to the profits arising from them, as an encouragement to men to pursue ideas which may produce utility, but this may or may not be done, according to the will and convenience of the society, without claim or complaint from anybody."
We can debate whether it's a good idea or not, but it seems that this limited monopoly was intended.
You clearly haven't Thomas Jefferson's explanation of how ideas cannot be owned, and the purpose of the artificial monopoly of copyright. Karl's post below details it quite succinctly. In your example, you own a piece of paper with the idea on it, not the idea. Once I read the idea, it's in my head as well. You can't undo an idea.
