We have no problem doing this in other areas. Airline safety, for example, is analyzed quantitatively by assigning a monetary value to an individual human life and then running the numbers. If some new safety equipment costs more money than the value of the lives it would save, it's not used. If a rule would save lives in one way but cost more lives in another way, it's not enacted. A famous example of this is the rule for lap infants. Requiring proper child seats for infants on airliners would improve safety and save lives. It also increases cost and hassle for families with infants, which would cause some of those families to choose driving over flying for their travel. Driving is much more dangerous and this would cost lives. The FAA studied this and determined that requiring child seats would be a net negative because of this, and that's why it's not mandated.

There's no need to overcomplicate it. Assume each life has equal value and proceed from there.
