I don't think it is a reasonable or realistic solution to just ban generative AI. We can enact and enforce regulations that protect artists' copyrights, but we can't say that "AI art" is not allowed. That isn't how our system works or has ever worked. It's unfortunate, but it was also unfortunate when Walmart killed mom and pop hardware stores and whatever. And like with Walmart, the lion's share of blame goes on the consumer. If the consumer is happy with crappy AI art, the artists or the regulating body can't force them to buy the more expensive handmade stuff.
