But, you know, in simple terms, if everything is happening the same way every time you replay with the same starting conditions, that is in a very straight forward way what it means for something to be deterministic, right?

Yeah, if every time you reset the system to the same initial conditions, it evolves in exactly the same way, then in the most straightforward sense, that’s what we mean by a deterministic system.
The extra philosophical layers we discussed—about high-level properties, rational norms, and interpretation—introduce complications about how we describe and explain what’s happening, but they don’t change the basic fact that, at the fundamental level, the system itself is unfolding in a fully determined way.
Would you say, then, that the distinction you're drawing is less about whether the system is deterministic and more about whether determinism at the physical level is the right kind of explanation for high-level rational agency?
Determinism doesn't have a whole lot of criteria. It really doesn't matter to me what you wrap your concepts in, no matter how complicated you want to make it. Supervenience, norms, multiple realizability - all very worthwhile, I'm sure, for you to think about, but it doesn't change the simple criteria of determinism - if you are guaranteed the same output from the same input, then it's in the most plain straight forward way deterministic.
(I didn't get a share link when I asked before, so I just asked again. Slightly different response the second time around.

The point I was trying to make is that it's not outlandish or an unfair manipulation of language when I say, the criteria of determinism is simple, it's simply, if you give it the same input you get the same output. If you start in the same state the next events happen the same too.
It doesn't matter what you want to tack on top. That criteria isn't concerned with any extra layers of analysis you'd like to do. You can do them, you can not do them, the simple criteria of determinism doesn't mind either way. If a system meets the criteria, then it's deterministic.
So if you believe free will exists in that system you described - that system where, given the same starting state you get the same events after - then as far as the logic in the op is concerned, you're not a libertarian, and it's not arguing against your idea of free will. You semantically think it is, because you call your idea "libertarian free will", and the article uses that same term too. But I personally wouldn't call your concept of free will presented here "libertarian". I would call it compatibilist. And you're right when you say it's not vulnerable to the intelligibility argument.
