No, in the US AI output is ineligible for copyright not because "art models are just regurgitating stolen concepts", but because only human created works are eligible for protection.
>only works created by a human can be copyrighted under United States law, which excludes photographs and artwork created by animals or by machines without human intervention

Or to not use a comma, to cram two incomplete sentences together whatever #FUamBOT =P
When people start pointing out spelling/formatting (in comments, no less...)... I'll typically just keep participating in discussions, elsewhere.

I recently purchased a GPU capable of running 16GB models (5070Ti), so definitely understand how easy it is to be susceptible to bot/AI comments. This stuff is really powerful/convincing. It replaced a decade-old machine, and runs Ollama/Qwen/Mistral insanely responsively.
But I'm still commenting pure humanly written. My PObox is listed in my profile, and I'll hand-write anybody back a similarly-efforted response card.
Formally speaking, it's not the case, though this is commonly misunderstood. Statistical models are definitionally ampliative, otherwise they wouldn't be statistical. One can argue about it until they're blue in the face, but it almost always comes down to a misunderstanding of what the models are, what the mathematics behind them is a description of, and what the underlying logical structures represent.
The thing is that the position and objection to these models isn't actually a substantial, reasoned position where the words have a direct meaning. Though it's dressed up like reason, it's not the point. It's a kind of metaphor. This actually does reflect the nature of intellectual property law. The legal framework is knowingly illogical at an object-level, because the end its seeking is completely divorced from the means. It has to be, because the idea of intellectual property is absolutely unjustifiable in-and-of-itself. It's just a useful legal fiction to make sure people are getting paid by commoditizing ideation. That's not a bad thing, it just means you have to be mindful that bottom-up reason will lead you astray when dealing with it.
