I don't understand this argument. It might not exist at all.
Why must it be the case that "at the level of the ultimate, the rules themselves run out and whatever is left transcends the rules"? Current quantum theory has no answer to the question, "what are electrons made of?". But it makes quite satisfactory predictions by treating electrons simply as point particles that follow certain rules. It says nothing more about them, but that might well be because there just is nothing more about them to be said, rather than there being something more about them which, however, is for some reason "unspeakable".
Well, you can either propose that the electron is
something that happens to have certain properties, or you can propose that it is
nothing that happens to have certain properties. The first is easy to follow but then begs the question of what that something
is. But the latter introduces all kinds of ontological questions and issues and certainly does not seem like a more rational model. Remember that QT is just a model, and whilst it is certainly predictive (at least certain forms or parts of it are) a model of the behavior of something is not the same
as the something. It's the old map and territory issue. QT is a map, it is not the territory. No matter how good, accurate, precise etc., a map you have, having a map is
not the same as direct experience of the territory. The rules certainly apply (to the best of our knowledge) to our interaction with the territory - but the rules cannot predict our personal perception or "experience" of the territory. It is in that sense that I say that the rules do not apply. The predictions of the model also don't tell us
why those things happen.
As I said before, pragmatically the best thing to do is to accept the model and certainly to try to expand knowledge to the best extent possible. But at the same time if we fail to recognise that (all) our knowledge
is just a model, then I believe we're skirting dangerously close to the kind of dogmatism that religion is accused of.
Anyway, the map is knowable, the territory is experienceable but
unspeakable - because you cannot pass the actual territory to someone via speech (or thought or reason), you can only pass a
model of it that way. The two are separate and distinct.

I agree that it's probably worth exploring, in the sense that then you'll be able to say, "hey, I've had this interesting experience that otherwise I wouldn't have had". But I don't see what sort of knowledge it will give you, besides simply the knowledge that such an experience is possible. What would it give you knowledge of? There's nothing "out there" that's causing the experience, if it's just due to some chemicals in your brain.
My point was not specifically that it would give you external knowledge, but it might give you some knowledge of your own mind or your own personal relationship to the world. I am saying that some people might consider the experience to be of value in and of itself. For example, you could say that the Mona Lisa is just some oil and pigment thrown on to canvas (i.e. a collection of chemicals) so it's value is simply the quantitative total of the cost of those materials. Others would disagree and insist that it's a great work of art and that its value is priceless. Who is to say that one judgement is superior to the other?
Plus of course has anyone shown any
evidence that religious experience (in the most general sense)
is a chemical imbalance in the brain? I'm not talking about wierd states of altered consciousness, I'm talking about everyday stuff.
My own view is that our "self", our consciousness and everything else we associate with being human
is simply a set of chemicals and interactions. But, having said that, does anyone, even the most ardent atheistic skeptic, believe that we are not more than just the sum of our parts? Would it be legitimate for me to kill someone I don't like and simply dismiss the matter as a case of "disposal of waste chemicals"?

And if not,
why not, if all we're talking about is chemicals?
