Seems to me that the underlying reasons, beyond the externalities Buck mentioned, are if your personal ethics have some combination of the following four qualities:
Terminally valuing people not dying, independent of opportunity costs
Valuing a lifetime of 2n years more than 2 lifetimes of n years
Valuing oneself more than others at some multiplier (assuming reflective stability)
Deep, persistent, reflectively stable fear of death
I am like this. I'm pretty sure oge is like this. It seems like there may be some philosophical barriers here. I definitely think that hedonistic utilitarianism violates 1 and 2 outright, and strongly discourages 3 and 4. As a preference utilitarian, the strength of 1 and 4 outweigh the costs to me.
