You think that smallpox, plague, tuberculosis, and other infectious diseases were major killers of pre-technological hunter-gatherers? I don't think that's correct. But you're certainly right about the problems with child mortality, maternal mortality, birth control, and infected cuts. I think it's not a given whether or not these are necessarily deal-breakers (personally I think the maternal-mortality-plus-birth-control combo is the most horrifying, but YMMV), but they're certainly very huge problems. Very huge problems. But I am not so sure you're right about problems with the justice. Again, GP didn't talk about the wonders of 15th-C England or 3rd-C Rome (never mind the really bad eras), they talked about pre-technological hunter-gatherer societies. Since "justice" is just a fiction we've come up with to try to match our evolved intuitions, my guess is that we'd be happier with the justice of that era than we are with the justice of the present era (and I agree that the present-day first-world situation is much better than pretty much all of the alternatives in the last 10,000 years). But you made a particular claim here, that "everything we know about criminal justice tells us that small insular groups of people are actually terrible at justice", and so maybe you have some references you'd care to share that could help me understand how right you are. I'd appreciate that. Personally, I, too, am a pretty big fan of printed books and (the output of) looms. (I mean, I'm actually a big fan of LCDs, too, but I think that's a less obvious win.) But I think that your final paragraph is basically begging the question. My understanding is that existing hunter-gatherers (the very very few of them that there are) are actually happier.
