Dear Lev
I understand your reasoning but let me explain mine in more detail because there are more things to consider. Possibly I will be somewhat boring in this attempt to clarify the subject as much as possible.
First, let me clarify that I did not say that physical laws are as simple as possible; the assumption that I considered is that the Universe is as simple as possible. This does not imply that physical laws are as simple as possible; truly, such a statement is meaningless - at least I can't understand it. Physical laws are a consequence of the nature of the universe.
What allows one to assume that the universe might be "as simple as possible" as a working hypothesis? The fact that we cannot assume anything else. If we consider the possibility of assuming differently, then whatever conclusion becomes possible - therefore meaningless.
Physics is always searching for a conception of the nature of the universe as simple as possible; that has led to the discover of the atom, then of particles, then of quarks; an endless quest towards simplicity.
In spite of all this, I agree with you that the assumption of the simplicity of the universe is acceptable as a working hypothesis but not to support conclusions. Furthermore, we cannot conclude from this argument of simplicity that a model of the universe has to be "understandable". I have a quite different reason to consider so but I did not want to mention it because it can be interpreted as arrogance, which it is not. That reason is that I succeed to "take the magic out" of the Cosmological model, of Relativity theory and of a considerable number of phenomena; therefore I think that "non-understandable" models are the result of their assumptions and not evidence that the universe is non-understandable. You can verify whether I am correct or not by seeing one draft paper I have on vixra (vixra.org/abs/1107.0016 ) and another one on the arxiv (arxiv.org/abs/physics/0205033 ). In both cases, the cause of the peculiar properties we have been attributing to the universe is the dependence of standard length units with motion, field and time. We can always model data considering that standard units are invariant, provided that we can add ad hoc parameters, like dark matter and dark energy, or we can consider peculiar properties, like spacetime properties, and to consider that there is no "objective reality.
I think that "non-understandable" mathematical models of data are an essential step in the discovery process, allowing collecting and organizing data; then we must start the second phase of the discovery process, which is to put theory aside and to deduce a new paradigm from data - the deductive-empiricist phase of the process. The fact that a model is non-understandable is a proof that it is based in wrong assumptions, not that the universe is non-understandable. Of course that this is just a personal opinion, based on my personal experience, but also is the opposite one. Note that by considering that the universe we know by now is still understandable does not mean that it can be explained by some simpleton reasoning - on the contrary, it is amazingly subtle.
I apologize for only now answer you but I had not seen your reply. I took a quick look to your paper. What I can say by now is that nothing of what I say contradicts your beliefs, just your line of reasoning and arguments, namely in what concerns the tuning to a goal. Maybe the universe is fine tuned to a goal, but I think that is not as you think, that things are much more sophisticated. I put a commentary in my blog addressed to "all" but written thinking in all the persons that follow a certain line of reasoning; maybe you can understand me better after reading it. To clarify all the differences between our lines of reasoning requires a long discussion but I am at your disposal if you are interested in it - my email: alf.g.oliveira@gmail.com.
I want to thank you this discussion; my goal in this contest is the exchange and discussion of different points of view, which requires that we assume our differences openly - as you did.
Best regards,
Alfredo
