I don't believe in MWI, but I try to understand it, and I can't get this to make sense. Reproduction is made conditional on some quantum event, so that it happens in some futures and not in others - OK. These futures are supposed to be in coherent superposition - not sure what the point of that stipulation is; is the idea that the separate futures are given a chance to recombine at some point?? But they can't recombine unless they come to resemble each other, which is a bit of a problem when one future contains lots of people who don't exist in the other one! And finally, doesn't this situation result in a Malthusian scenario in the branch which does reproduce??

Making reproduction conditional on some quantum event sounds like a reproduction lottery to me. It reduces the birth rate, but the main difference from other means of population control is that the decision about who has kids is made randomly - resulting in an eventual decline in genetic quality of the population.
