You can’t talk about Mickey Mouse and show him on screen because that’s a copyright violation. Similarly, you can’t make cat GIFs if you don’t own every single element.
Culture is more and more seen as “property”, even if the two are preeeetty different. We see ourselves and the sole “original” creators, when in fact we just build on what has already been created. remixing and recombining stuff already made by other people. Culture is a conversation, not a monologue.
