You're right.  I meant to type, "I agree there is NO reason to..."

I think that an observer must be physically instantiated - that seems well
supported empirically.  As it is used a "observer moment" seems to mean a unit
of subjective experience.  That there is an "observer", i.e. something with
continuity over many such subjective experiences, must be an inference or a
construct within the theory.

I don't know that "we have to".  I've know idealist who suppose that our
memories are part of our immaterial spirits.  But they have a hard time
explaining the limitations of memory.

But if, for each subjective experience, there is no way to uniquely associate
it with a sequence of subjective experiences, i.e. every such experience has
many predecessors and successors, then I don't see how such sequences can
constitute a particular person(s).  It seems in these discussions that the
existence of such sequences corresponding to a particular person, an
"observer", is taken for granted.  It is a natural model given that observers
are physical things - but it is problematic if physics is thrown out and you
start from nothing but "observer moments".
