Art is faulty by definition.
Art is about creativity, which means deviations from perfection, or faults. If I run the same document through a printer that works perfectly 200 times, I will get 200 identical documents.

That which is faulty is also chaotic, it grinds against what we instinctively know should be, it makes us want to fix it. Art inherently contains these qualities which are not beautiful.
