With ML there's the "M", machine, and that machine (and its algorithms btw) is owned by someone. If we back away from general concept of intelligence a bit, that owner is who can be held accountable. Maybe that would get them motivated a bit.

And with the robots.txt approach, I understand, there'll definively be some rogue AI that would parse and process that on purpose :)

As for "doing the same thing", well, kind of, yeah, we're back to the thousands years old copycat problem. But this time art/code creators don't want others having machine that could recreate years of work in a minute with a push of a button. Also, artists usually acknowledge who did they learn from or who's style are they trying to recreate... but that's an ethic thing..
