I believe you can't copyright a _style_ of art.

> no, you cannot copyright the Studio Ghibli art style itself. Copyright law doesn’t protect styles, techniques, or general aesthetics—like the hand-drawn, watercolor-inspired look with soft colors, detailed natural backgrounds, and whimsical vibes that Studio Ghibli is known for. It only protects specific, original works, like an individual film frame or character design from Spirited Away or My Neighbor Totoro.

And your answer... Doesn't seem to cover my question, I think. So the point of copyright is that the value of the style doesn't degrade?
