Because humans are not machines. Otherwise we would send machines to prison when they kill someone, right?
I see it like this:
Say you write a book. I assume you would find it obvious that I am not allowed to copy your book, replace your name by mine, and sell it, right? That's the point of copyright.
Now say I don't just copy-paste your book, but I run it through a software that replaces some words with synonyms (without losing quality or meaning), and I sell it all the same. Are you fine with that? I would tend to say that I am still abusing your copyright on your book.
Generative AIs can do exactly that, and the people using generative AIs don't have a simple way to check if the output they got is a slightly-modified copy of copyrighted material or not. All we know is that the AI is a machine taking the words in your book, processing them automatically, and generating a new text. Those are not humans who learned about the world and write down their thoughts, but machines that copy-pasted-and-modified words.
