You’re coming at this from a slightly askew angle. Consciousness is holographic - that is, it’s complex behavior arising in the interaction of a more complex system. There’s nothing “more” to it than what we see. The transporters from startrek, which destroy then reproduce exactly, would change nothing about your experience. You’re just a complex arrangement of atoms, and it doesnt matter where that arrangement occurs so long as it’s unique. There is no “you”, there’s just “stuff” stuck together in a way that lets it think that it can think about itself. A perfect reproduction would result in the same entity, perfectly reproduced.
