The problem with the above is that mimicking is done by another process altogether. No cells of the copy have come into being as a result of originals dividing or by being built by the original system. The only arbitrariness about that fact is that it is a truth that cannot simply be hand waved. If we cannot consider ourselves as us because our raw materials came from elsewhere, then nobody is anybody. We're all just part of the Big Bang.The notion of “take possession of” new materials is arbitrary. We could mimic this in the copying process.
