Identical abilities argument

Identical abilities argument is the argument that a cidentireplica will have the identical abilities as does its original or any other cidentireplica of this original. The proof of this statement is that by definition a cidentireplica will behave exactly like the original as long as it is a cidentireplica of this original. As a result any abilities that the original shows by way of its behavior the cidentireplica will also show as well. For example, if the original can play a piano the cidentireplica will be able to play the piano just as well. This piano playing will occur in the same places in the life of the cidentireplica as it did in the life of the original. There can also be many slight differences between the original and cidentireplica where the original and cidentireplica still have the same abilities. For instance, one atom in the cidentireplica being an isotope of an atom like carbon 12 rather than carbon 14. Considering how many atoms there are in the body there can be enumerable number of changes without changing the ability of the cidentireplica in respect to the ability of the original.

The "identical abilities argument" is used as part of an argument showing that a cidentireplica can replace an original for objective and subjective purposes If every aspect of a person is duplicated by a cidentireplica of it, then is it not replaceable for the original?
