This is the most braindead take and aibros keep pushing. Your 'AI' model is NOT A PERSON and therefore it is different.
My point being: it's exceptionally hard to create laws that deny precisely what you don't want and allow precisely what you want, without quickly getting into details that bring the entire law's assumptions into question. Here being "because an ML training is not a person, it has no right to scan the web".
Also on a whole different scale and instead of supplementing the web content it’s devaluing it to a degree.
Basically you're assuming the agenda of the operator, saying "that's bad an shouldn't be allowed". But I see the web- except for things specifically labelled with standard copyright disclaimers- as effectively a large corpus of publicly available data, "in the market square for all to see".
