Arguments
2=2 argument
Two identical things can be the same as concepts while different as objects. That gap is why consciousness, which is a pattern, can recur even though a particular brain cannot.
When you write "2 = 2," both sides refer to the same number as a concept, but they are two separate symbols as objects on the page. The number two and the numeral "2" are not the same kind of thing. A concept can be identical across many instances while those instances remain physically distinct.
The same logic applies to consciousness. Your conscious experience is a concept - a pattern, a structure - and that concept can be instantiated in more than one physical body. Two bodies can each produce the same "you" the way two separate tokens of "2" each represent the same number. That gap between concept and object is exactly what makes consciousness recur.
What this means
Because you-as-concept and you-as-body are different kinds of things, your consciousness can outlast any single body that produces it.

The "2=2 argument" is an argument for showing that the structure and functioning of matter is different from the matter itself. It is taught in mathematics that two identical numbers are identical. Yet two identical bodies are not identical because they are in different places and made of different matter. But the number two is a concept that is not in a unique place or time unless it is on or in matter. For example, the number two is represented as a symbol painted on a block of wood or carved into the wood. It can also be the caulk on a blackboard or the ink on a paper in the shape of the symbol that represents the number two. The functioning of the brain represents the concept of two in different ways. Yet the number 2 is not physical so it can have no physical identity. Where a replica of you is not you, no matter how exact of a replica it is, it can still produce concepts that are necessary and sufficient for your conscious existence.
Certain concepts can be identical without the matter that they are associated with being identical. These are concepts like structure and functioning, consciousness and ixperiencitness, or redness, cuteness, loudness etc.
