Even if we suppose that a much smaller fraction, let's say 10%, disappear in the Rapture, it would still be a grand scale economic catastrophe.
Assuming we assign a negligible probability to the Rapture ever happening at all, then as I already stated, that would mean that the person setting up the insurance policy is putting in time and work, ensuring others' peace of mind, for no compensation at all. This is the most salient of the points I raised, and any specifics of what would occur in a hypothetical Rapture event are irrelevant to it.

Having thought it over, I'm OK with the ethics of this service.
