>"most people" are people that have grown up in a civilization that has some legal understanding of "intellectual property" and the economic effects thereof, so their intuition is already pretty skewed towards the status quo.

That may be so, but I still claim that there is something intuitive in supporting the idea that content creators be allowed to "own" their creative work. Doubly so if you live in a society that allows ownership (of things, or land), because it's a very short conceptual jump from one to the other.
