Rubbish. You're just assuming the user put in little effort. It's perfectly possible to put in little effort using pen and paper too. The end result looks less like a final piece, but it's probably equally close to what the artist tried to express. No one who uses downloaded brushes in Photoshop write the code for importing and drawing with those brushes. Nobody who uses photo textures wrote the code for their cameras. Nobody who uses Blender wrote the code for the light transport that happens when you hit render.

Drawing a style guide, drawing the composition with a sketch, and paint overs are all completely normal parts of the process when using Stable Diffusion, and none of that is where the creativity comes in.

because you didn't write the code for the algorithm, you didn't make any of the training data pictures, and you didn't do anything that could be considered 'creative' or 'talented' to make it

Did you invent the paint brush?

Real fucking artists that put hours of time, effort, and creativity into their work deserve to have it protective.

Working hard does not have any intrinsic moral value. That is puritanist . There is no value in suffering.
