I would support using AI for plenty of things, art included. Most commissioned art today isn't exactly soul shaking stuff teeming with creativity and emotion, it's corporate graphics, design templates, ads, assets for video games etc, I personally don't have a problem with using AI for that the same way I don't have a problem with my clothes being made with sewing machines.
As with everything else, the problem isn't the technology it's the economic system.
Also I don't think many people are profiting off of copyrighted AI art directly unless it's in service to those other things I mentioned.
