I agree with you on the distinction of copyright and patent with respect to independent invention. But that's just a human-made distinction, in the USA. Whoever wrote the laws didn't get independent invention enacted in patents.
I also agree with your reason for "IP" as a misnomer.
I wanted to speak in a general or philosophical sense. not in a legal, specific sense. The internally-inconsistent concept of "Intellectual Property" founders on the rock of independent invention, if you reason from first principles, rather than attempting to propagandize your way through to some kind of state-enforced monopoly.
