Eh not impossible… just very improbable (in a given world) and
certain across all worlds.
“Very improbable” is the typical assumption with MWI, but I think that
it is mistaken in most cases dealing with complex systems.
Each wave-function sets limits on what can occur. Wave-functions don’t
have infinite extents, there are areas with zero amplitude. Each
additional wave-function that must meet specific requirements further
restricts the possible outcomes. In general, the likelihood of failing
to meet the simultaneous condition grows exponentially as the system
size grows linearly.
Since quantum survival (avoiding death in some worlds, in some
meaningful context) will usually require a very large number of
quantum level alternatives to be simultaneously selected for, quantum
survival will almost always be impossible.
A person who experiences quantum survival once is very lucky, but
almost certainly won’t survive the next time. A person who fails to
experience quantum survival never gets another chance.
So my conclusion is that quantum immortality is impossible, not just
very improbable.
Your logic here makes no rational sense. Your saying things which can be proved to be false.
Firstly I accept your premise that some things have zero probability. The wave-function doesn’t mean literally anything can happen
BUT
I strongly disagree with you when you start saying that simultaneously selecting for possible (but improbable things) makes them impossible because this makes no rational sense. Quantum events are independent of each other the fact that 1 radioactive atom decays doesn’t mean that the next is more or less likely to (unless they interact of course but I am ignroring that) nor is there a cutoff as to how many atoms can decay.
If a random event has a non zero probability of occurring, then a googleplex number of those events has a nonzero probability of occurring, in ANY COMBINATION.
I am a mathematical biologist, have a think about how many random mutations had to occur to create you.

Wait, is there proof for wave-functions not having infinite extents?
I always thought that the idea was similar to a normal distribution curve, where any value could be possible, just some are extremely unlikely.
