If the independently behaving parts don't have some underlying common
physics (e.g. they could in principle become different from time to time
according to some simple rules, but generally are the same), then there
will be so many degrees of freedom from the independently behaving parts
that arguments about why a system does what it does will be
quantitatively as good as any other.    Luckily `environments' can have
stable observable properties that can be treated as hard, fixed
constraints.

It seems to me self-consistency and reflectivity isn't a problem,
provided the list of exceptions can grow indefinitely or that the
individual exceptions can be ambiguous.   Consider the popularity of the
legal profession.  ;-)
