> And a human artist doesn't need to steal million pictures to learn to draw.

They... do? Not just pictures, but also real life data, which is a lot more data than an average modern ML system has. An average artist has probably seen- stolen millions of pictures from their social media feeds over their lifetime.

Also, claiming to be anti-capitalist while defending one of the most offensive types of private property there is. The whole point of anti-capitalism is being anti private property. And copyright is private property because it gives you power over others. You must be against copyright and be against the concept of "stealing pictures" if you are to be an anti-capitalist.
