Why is our universe made up by laws we don't define or know the variables for? Not inherantly at least. I'd say this fact would imply that it's because we over value consciousness. We are nothing more than the physical state of that matter that is our mind, and the experiences that make it up. If that is the case, than the only way to explain the existance of consciousness at all is that it's a network of data that runs through our neverous system, and stores itself, and processes that data in our mind.So we're computers. We're a biological program who's purpose is to ensure the health and life of our cells, and make sure that we reproduce not becsaue we have a purpose, but simply becasue if we didn't, we wouldn't exist. We are a self perpetuation virus in that case, and when we die, it's light's out to not only us, but our universe.
Of course, I don't purport to be a leading authority on reality. Another suggested read would be Chris Langan's CTMU (Cognitive-Theoretic Model of the Universe). Apparently he's the smartest guy in the world, by last reports. I will try and answer some of your questions the best I can.
There is no "physical" reality. There is only information. Consciousness is the computer. It acts in such and such a way, because that's how it's supposed to. Think of things as processes, but not static equations or such. Subroutines and whatever computer jargon you want to relate to. Campbell uses simulation for his model of his theory. He quite aptly notes that there are just unknowable things. Even the smartest bacteria will only know a little bit and its cosmology would be rather restrained to the tract of the intestine it may inhabit. It would not know it was in a body, or what rain and sun or food is.
Imagine being "outside" the universe before entering it. Once inside, you forgot all about the program you wrote. The "character" in that universe is limited to the knowledge and awareness you programmed it to have the capacity for. Include in that program the fact you forgot you programmed things in the first place. Add to the program, like I said, the inherent inability to even know how to program, even if it found out it forgot it did, as a key restraint of that character. How would that entity know?
How can an entirely homogenous environment, all things are the same, but really there is just one "thing," become multiple from a single whole? It has no way to define itself as separate or have any basis for comparison. You'd have to segregate partitions of your undifferentiated state of consciousness by forgetting things in a selective manner, which may find definition by the rules or physics of the universe.
I am going to turn too abstract, I think. But ...I guess it's a start. I hate typing huge long things, but you just touched on a subject I've done a long, long study on.
