The problem with (3) is a general problem with multiverses. A

That implicitly assumes a digital universe, yet the theory that
suggests it, quantum mechanics, is based on continua; which is
why I don't take "the multiverse" too seriously.
It appears that our brains are finite state machines. Each neuron
can either be "on" or "off", there are a finite number of neurons,
so a finite number of possible brain states, and a finite number of
possible mental states. This is analogous to a digital computer:
Not necessarily. A digital computer also requires that time be
digitized so that its registers run synchronously. Otherwise "the
state" is ill defined. The finite speed of light means that
spacially separated regions cannot be synchronous. Even if neurons
were only ON or OFF, which they aren't, they have frequency
modulation, they are not synchronous.
Synchronous digital machine can emulate asynchronous digital machine,
and that is all what is needed for the reasoning.
True, but only going to a level far below a "state of consciousness" so
that in this finer level of emulation there are no longer identifiable
states of consciousness. Rather "states" are coming into being and
fading away, with various overlaps.
