Throwing out intellectual property absolutely would stop the vast majority of the art made today from being made. We've had an explosion of art once we entered into an understanding that the creators of a work have control over how that work is used. Getting rid of that would kill film, television, and music. Would people still make these things? Yes. But not nearly at the quality or quantity we see today.
No, that's not an interesting point because the obvious answer is yes, more art is generally better than less art.
Either way, it's not up to you to decide utility arbitrarily. Besides, if the art is bad, why are you pirating it in the first place? The problem is that people want the art too much, and are willing to break the social contract in order to obtain it.
