Please explain how your ideas follow from Hitoshi Kitada's theory
of Local Time. Keep in mind that most of us are not familiar with that
theory.

Also, any quantum computer or physical system can be simulated by a
classical computer. So in theory, even if human minds are quanum
mechanical, we can simulate a complete human being from conception to
adulthood in a classical computer, and then copy him to another classical
computer, so the no-cloning theorem doesn't prevent copying of minds.

Besides, the no-cloning theorem only says that there's no method for
duplicating arbitrary quantum systems in such a way that no statistical
test can tell the difference between the original and the copy. There is
no evidence that the information that can't be copied are crucial to the
workings of a human mind. I think current theories of how the brain works
have its information stored in macroscopic states such as neuron
connections and neurotransmitter concentrations, which can be copied.
