First of all, you can’t make a perfect copy. Second of all, faking paintings and advertising them as original just so happens to be illegal. Can you give me a reason why it should be acceptable when AI does it?

Your comparison of taking inspiration and literally generating something from someone elses image is the most braindead take on ai I’ve read. As a human you can’t replicate someone’s style to the extent that ai does. And if you are drawing from reference and trying to make something as close to the original as possible then it’s normal to give credit (with digital art at least).
