It's beyond contest that the g factor is real in part because it's a statistical inevitability in any series of related tests, be they for intelligence or product/market fit in automobiles. It's an exploratory statistic, a hint at underlying causality; it is not a dispositive revelation about the structure of human thought.
Sure: there's a battery of general cognitive tests, and if you smush data sets together a dominant factor will emerge. And?
This is exactly my point. It's tautological to argue that IQ isn't correlated with intelligence. It is, definitionally. You seem to acknowledge this so perhaps I don't understand your original comment.
I just don't think there's anything meaningful about that. Group of related tests is related. Ok, now what?
