I still don't understand how you can use appropriation about art and culture inspiring and developing off each other.

All artist, all culture is based on something else, usually inspired or formed by society around the artist. Do you suggest we fine comb all culture and artistic expression, lock it down and then form a committee shutting down anything that can be found anywhere else? We also have to find the earliest expression of that art form and make sure they keep the rights to make anything in that expression and everything else is banned.
