This strikes me as a series of excuses for not biting a bullet. The thing is… it’s not a bullet that would need to be bitten anyway.
We don’t have (yet) any real explanation of the Born probability rule, it may come out that the worlds with very very low probability just don’t “really exist”, as the mangled worlds hypothesis claims.
Sure, it is possible that mangled worlds or something else that made quantum amplitudes discrete in some way would influence our preferences but we don’t have a solid reason for assuming this to be the case. It is worth looking at how quantum mechanics actually appears to behave and evaluating preferences accordingly.
Only when a very small quantum-level event can have a huge macroscopic effect (like Schroedinger’s cat experiment) do you really have worlds with different macroscopic outcomes. And yes, you can have such “chaos theory” effects, like the butterfly effect, even we don’t artificially devise experiments that way, but they aren’t frequent.
Sure they aren’t frequent… but the very premise of the question the post asks relies on implicit selection effects that select for specific highly improbable events. It for some reason arbitrary selects only the freakishly unlikely “live” branches and chooses not to care about “die” branches. This gets progressively more extreme the more ‘immortal’ the actor is considered to be. So sure, Schroedinger’s cat is a contrived circumstance and doesn’t happen naturally very often, but they are just the kind of event that comes into play with “immortality” selection.
