Hi Steve,
Moldoveanu's contention that the laws of physics are invariant under additional degrees of freedom is fundamentally wrong-headed.
It would deny quantum mechanics any dimension at all, save the 1-dimension real line. And that is correct as far as it goes -- metric spaces. I agree that is the proper domain of quantum mechanics (as my proof for what I call Khrennikov's theorem establishes). A very useful concept for information theory, not for foundations.
The Hilbert space quantum formalism is two-dimensional. M's translation to a "para-Hilbert space" deprives complex analysis of its power to generate both real and complex solutions, since he has discarded the fundamental theorem of algebra. In any case, if my informal proof is correct -- the physical existence of reversibility in 2 dimensions contradicts irreversibility in 1 dimension, and favors a topological theory.
In any case, though M implies (reductio ad absurdum) that the only physics is either classical or quantum, there's nothing classical about his theory. Nor even necessarily physical.
