"For example the prior probability of someone being born with your specific genetics is so close to zero it’s not worth mentioning." I don't understand what this has to do with distinguishing between individuals and populations. You could just as well say that the probability of a whole population being exactly as it is, is even lower. You reference "polluting the context of an outcome with unrelated contingent information", but isn't that what you just did? If you think that confuses the issue, then what's the point?
