What if they destroyed and reassembled only 0.5% of your brain? What's your dividing line? 0.36%? 0.0188%?

I think you're misunderstanding that words are social constructs which can point to abstract categories rather than necessarily single concrete objects at a particular moment in time (although words can also do that).
Like if you have multiple tennis balls, each ball is still a tennis ball, despite each ball being different, because "tennis ball" is a social construct and an abstraction that's an indirection to a certain concept. In the worldview I am talking about, the word "you" is an indirection to a mind that is indistinguishable in content and experience from the one you have right now, with the property of fungibility across modalities, time and space.
