What would happen if consciousness could be separated from behaviour
is that your brain would go in one direction, controlling your body,
while your mind would go off in another, as a helpless spectator. That
would mean consciousness is not due to physical activity in the brain,
contradicting the single initial assumption. If you grant that
assumption, then consciousness is provably what you call a byproduct
of intelligence.
