Not at all. Criticism is a good thing, particularly when asked in the
open-minded way you did. The particular questions you've asked, I've
already thought about, and mostly addressed in the book, but someone,
somewhere is likely to ask the question I can't answer, and from that
one can learn!
The "derivation" of QM depends on all the principles previously
introduced: multiple realities, observer measure (and the consequent
Occam razor theorem), TIME, Darwinian evolution and the anthropic principle. It
also depends on some (ie non-contentious parts) of set theory and the
Kolmogorov probability axioms, but that is seomwhat technical, so I
relegated this to the appendix (and the Foundations of Physics paper).
Vic's "point of view invariance" principle is a special case of Occam's
razor - one should expect invariance as the most general/likely
situation, but some symmetry breaking is required by the anthropic
principle. At the time I was writing my own book, I had only read
draft chapters of Comprehensible Cosmos, so wasn't quite aware of the
importance of POVI at the time.
Cheers
