Imagine your replicate is put in a world without oxygen. It would very fast feel rather different from you despite being identical. You assume consciousness is an inside state which can be copied. But it could as well be a process in constant need of an external influence which might refuse to connect to your replica. Like the difference between standing and flowing water - watched only in one instant they might seem identical. And while the solution would certainly be to copy the world as well, as long as we can't define consciousness we can't really say for sure how much we would have to replicate.
