In theory intellectual property is a great idea, it protects artists from being devalued. In practice, with bad actors, it is nothing but a way to hold a monopoly over an industry, if someone comes up with a new song you can just sue them for using a note that also appeared in one of your songs, and because you have the money of industry on your side you will be able to outperform your victim in the courts. Now you are the controller of what people see and hear, you are god.
