I wasn't joking when I corrected your factually incorrect statement. The source of that training data & eula involved was linked earlier in 124 & 136. Here is a section

Im not sure where you got the impression that I was talking about what seems to be one specific (if unnamed in your post) AI. I was speaking in general and no, not every image AI had entirely ethically sourced content.
Though even with your example, that doesn't prove much of anything given basically no one consciously consents to the TOS' of huge sites like Pinterest, which is a problem you're actually giving evidence to in the section you quoted.
We are inundated with art through most of our lives.
Sure, but that doesn't mean you need to have seen Art before you could make it. Afterall, lost to the sands of time is the singular human (or more accurately, human ancestor, as our cousins had art before we existed) who invented the very concept of art, and could have only taken inspiration from the world around them and, for whatever reason, felt compelled to mimic it in what rudimentary way they could.
So to suggest that only one proto-person had an original thought hundreds of thousands of years ago and everyone else is effectively just a derivative is very demeaning to what artists attempt to do today, and as said earlier (I think, I've had this conversation more than once tbf), it implies a certain amount of contempt for what artists actually do when you speak of it so reductively.
Yes, culture does influence artists, and its why cultures even today still have a distinctly united style (or styles) amongst their various artistic movements, which is now globalizing via the internet as once isolated movements interact with others across the globe.
But all a person strictly needs to spontaneously make art of some form is merely the impulse to mimic what they see in some form or another, and nature on its own is beatiful enough to inspire this impulse. Its not a coincidence that the first religions were so heavily steeped in natural imagery, and the earliest examples of art that we've found almost always look towards animals, nature, or indeed, the female form.
And ultimately, it has to be brought back to what was being argued. The nonspecific They are arguing that what AI and Artists do are one in the same. That is not true, and bringing the reality of how culture influences art (and vice versa; its not a one way street) is really neither here nor there.
As explained, the first things we made art of were explicitly not art; unless of course you want to go the Creationist route, but then we'd be completely off the rails as far as the topic goes.
