If I would create a piece of art and you'd just use my art in attempt to make money for yourself, I would try to stop you with the tools I have. And you of course could go crying "BOO HOO YOU ARE TRYING TO MONOPOLIZE ART".
As Counter to:
Art isn't being monopolized. Anyone can create art if they want without being attacked by artists.
Except that you didn't say nobody can copy "art" without being attacked by the artists. Ie Monopolizing over the idea, when did you think we stopped talking about Monopolizing ideas? The moment you responded and denied that monopolizing over ideas happens? The conversation doesn't change simply because you entered into it without any substance what so ever besides a denial that monopolizing over ideas happens.
