If you’re prepared to say you’re immortal because even if you die you’re still alive in some other branch, it seems like you shouldn’t even need quantum mechanics. You’re immortal because even if you die, you’re still alive in the past.
Sure, but the subjective experience of being my past self will never causally follow from my subjective experience of being the current me, so I don’t care.
Put another way, you’re talking about timeless immortality. I’m talking about real immortality.

The difference between “never” and “with order epsilon probability” is of order epsilon, I wouldn’t worry your head about it.
And you’re not talking about real immortality, that’s my point. Quantum immortality is no more real than timeless immortality, and arguably less.
You’re talking about a different notion of immortality. As it ignores probability, it doesn’t seem to capture the usual concept very well.
For sure, whatever kind of “immortality” it is it certainly isn’t something I would tend to describe as “real”!
