That’s about consciousness, which is a much larger claim than the self being an illusion

I don’t agree. Care you defend this claim? Your assertion that you can have consciousness without a self (ego death) seems more personal spiritualism than argument.

In theory, a conscious being could exist that’s always in a state of ego death, and have no understanding of the self and be utterly confused by why people find anything unintuitive about the teleporter paradox.

In theory like modal possibilities, or in theory like you genuinely believe such a person can exist? I’d love to hear why.
