I think my point is, maybe there's no such thing as continuity of experience (since we sleep every day) and consciousness itself may be an illusion. With an instant replacement, and also with a large distances, it makes it clear this is not me any longer, but if I replace my neurons gradually with digital components it's essentially equivalent to what is already happening with my brain cells, so it doesn't break the illusion. My identity and consciousness is an illusion and I just don't want to break it. I know that is contradictory and makes no sense, but that's the reason I would not use the transporter.
