The manifestation of that is ownership over ideas. If I recite the Harry Potter series to someone and they copy it down and publish it, they've violated copyright. That only happens because IP grants ownership over the idea (the story of Harry Potter) itself. I'm not sure if we are agreeing and just missing each other on the words, it if there is something more substantive between us?
