The comparision doesn’t work. Because the AI is replacing the pencil or other drawing tool. And we aren’t saying pencil companies are selling you Mario pics because you can draw a Mario picture with a pencil either. Just because the process of how the drawing is made differs, doesn’t change the concept behind it.
An AI tool that advertises Mario pcitures would break copyright/trademark laws and hear from Nintendo quickly.
I don’t think how you interact with a tool matters. Typing what you want, drawing it yourself, or clicking through options is all the same. There are even other programs that allow you to draw by typing. They are way more difficult but again, I don’t think the difficulty matters.
There are other tools that allow you to recreate copyrighted material fairly easily. Character creators being on the top of the list. Games like Sims are well known for having tons of Sims that are characters from copyrighted IP. Everyone can recreate Barbie or any Disney Princess in the Sims. Heck, you can even download pre made characters on the official mod site. Yet we aren’t calling out the Sims for selling these characters. Because it doesn’t make sense.
