Consciousness is Fundamental The issue here is not merely terminological but conceptual, what is mental and what is physical? It's not as if there is an intelligible distinction not made between arbitrary stipulations as in: the mental is what-it's-like subjective experience, whereas the physical is something to do with what physics says, or whatever is concrete, and the mind is not concrete.
Our view of matter now is far removed from the old "dead and stupid" matter idea of the 16th century. It's no longer that, in fact whatever the physical is, has almost nothing to do with our intuitive ideas of "concreteness".
So, I ask rhetorically for the nth time, why can't the mental be physical? Why can't the physical be mental?
These terms are thrown around without much clarity, in my opinion.
But we can ask, is consciousness fundamental? Fundamental to what? To the universe? Does the universe have mind? I don't see evidence for this view. But there is no evidence against it either.
If by consciousness one means "what-it's-likeness", then I don't recall feeling anything prior to being born. That's the only "subjective" (but re-interpreted) experience I have of the universe, after conceptualization.
I see no subjectivity here. Is the universe intelligible to us other than through minds? Not that we know of. So, unless these issues are clarified - not stipulated - intuitions aren't going to help, as evidenced by these endless conversations.
