Explain a little more. I'm not understanding why the "potential impermanence" of death is a factor at all, much less why that potential impermanence is corroborated by the probability of existing in the first place.
To me it sounds like you're claiming that it makes us nervous that death might not last, and somehow realizing that being alive in the first place being improbable makes that nervousness worse. How in the world that would be the case escapes me, so asserting it as obvious seems like...too few words here to achieve any insight.
I could be misunderstanding, so more words to clarify would be appreciated.
The concept of infinite rebirth and suffering at varying degrees of consciousness is much more threatening than the concept of having a single conscious existence bookended by stable nothingness.
Stable nothingness is just modern-day materialist heaven. It's a coping mechanism that relies on your currently inexplicable conscious node of existence being the first and last across infinity/eternity.
