If all we have is observations and models and predictions, and the whole enterprise of trying to reason about whatever might underlie those observations is misguided, presumably abstract assertions like “there exists a single X” or “there exists more than one X” are also misguided except insofar as they can be grounded out in differential predictions about future events.
That is, I don’t see how the distinction you’re drawing here between those two superficially distinct accounts is at all meaningful on your ontology.

That is the minimal model I currently prefer, yes. And “the whole enterprise of trying to reason about whatever might underlie those observations” is not misguided, it’s useful for coming up with better models, but that’s all it is useful for. Assigning it any ontology is unnecessary.

I am not drawing any distinction, neither matters in the approach “build models and test them”. You are the one who started discussing some metaphysical “X”, I simply pointed out that your suggestion of a single “X” is not a requirement.
You raised the question of whether X refers to a “single coherent whole” entity or refers to multiple entities (e.g., multiple repeatably testable models).
Which, as I said, puzzled me, since my understanding was that on your account that’s a meaningless question. And it sounds like we agree that on your account it’s a meaningless question.
I’m still not really sure why you chose to raise it in the first place, but I hope we can agree that the proper thing to do with a meaningless question is to point out why it’s meaningless and otherwise ignore it.

As far as I can tell, you are the one who invented “X”, no? I never said I need it, just pointed out certain flaws with it.
I suppose it is not meaningless in any model that includes X, and the one I favor does not. I hope we agree on at least that much.
Tapping out.
