That's a historical accident of the times we live in. It used to be there was no way of paying a musician for a "product" as the musician would write a composition and after transcription it was "out there". I very much doubt J. S. Bach or Mozart could make the money to survive by being paid "per performance". In another universe, where near zero cost digital reproduction happened earlier, we'd probably think it a bit weird to pay a musician a fee to "own a copy" of their work in the same way we would think it weird to pay Gustav Eiffel a percentage for a plastic model or to look at a photo of his tower.
I don't think we should be guided in our opinion of what "should be" by the accident of where we happen to be now.
