You don’t really need an example scenario - just take YouTube, the largest source of creator content - it does nothing to prevent you from sharing the videos.

Ultimately if you feel like you’re being wronged DMCA should be used and not a programmatic approach simply because a program has no notion of who was right to begin with.

So in your example you say “my art”, but what if it were not? Should you not be able to post “your art?”

I believe people should handle people issues and computers handle, well, the other stuff.
