Sure, use piracy. We all understand what that means. But I'm not trying to define it out of existence, I'm trying to use the english language effectively. It's plainly not theft. And furthermore theres no such thing as intellectual property. Unfortunately you will never own any of your copyrightable creations. Your will just own a temporary monopoly on their reproduction in certain circumstances.
It's as simple as that. Thinking that you own any creative works is misunderstanding the law and society. Thinking that copying something is theft of it(or indirectly theft of anything else) is a misunderstanding of the same.
