Just like the estimates for building dams don't include the ripple effect of dying fish, dying fisheries, and the health impact on fishers. (Or the relocation of people to create dam lakes, leading to stress-related deaths just like Fukushima relocations might have...)

My point: Once you go into small and hard-to-quantify large-population effects, your error margins become ridiculous and you can pull out any conclusion out of your hat...
