There are positive economic externalities to public everything availability. We don’t live in this kind of world though, someone will always try to claim a larger share due to human nature.

Saying "Things are inevitably bad because of human nature" is just very weird, since we obviously do have good policies and we try to solve other problems like crime and poverty. It sounds like you already agree that this is good policy? You're just saying it's not politically feasible? OK, sure, we probably don't disagree then.

That being said, I’m not really interested in arguing about the political feasibility (or lack thereof) of having every resource being public.

I am obviously NOT arguing that every resource should be public. This discussion is about AI, which was publicly funded, trained on public data, and is backed by public research. This sleight of hand to make my position sound extreme is, frankly, intellectually dishonest.

there’s also a cost people pay to use these LLMs.

OK, keep the premium subscription going then.

What you’re missing though is that there is an extreme shortage of components.

There's a shortage, but it's not "extreme". ChatGPT is running fine. I can use it anytime I want instantly. You'd be laughed out of the room if you told AI researchers that ChatGPT can't scale because we're running out of GPUS. You seem to be looking for reasons to be against this, but these reasons don't make sense to me, especially since this particular problem would exist whether it's publicly owned or privately owned.
