Some plot elements seem somewhat goofy: So apparently some minor difference like the absence of fighting between different groups is enough to make a world like a Garden of Eden? There was no death and no struggle to survive in the biblical Garden of Eden story. But in real primitive societies there is death and struggle to survive. Quite the opposite of any paradise or Garden of Eden. In a society less advanced than western society in the last two centuries or so, most of the people who were born died of various diseases in the first few yeas of life. People who lived to be teenagers or adults were a minority compared to people who died as little children. And a large proportion of the people who were born were actually killed or left to die by their parents in the first few days of their lives. https://en.wikipedia.org/wiki/Infanticide So the accepted minimum estimates is that in primitive societies at least 15 percent, and possibly a much higher percentage, of all the people born were murdered soon after birth. And this would have been the practice among hunter gatherers for tens or hundreds of thousands of years until agriculture was developed. Agricultural societies could raise all of their children (who survived various diseases) to adulthood and didn't need to murder newborn infants. And so various agricultural societies gradually dropped the practice of infanticide, slowly over thousands of years. So if that planet is anything like Earth, and the natives look a lot like Earth humans, and Caucasians at that, it is possible that the villagers no longer practice infanticide (though they might still practice it) and it seems very probable that the Hill People still do practice infanticide. But even if nobody on the planet ever practiced infanticide, childhood diseases should kill a majority of all the people born while they are still little children. And they will continue to suffer such high death rates for centuries or millennia to come until the society becomes advanced enough to prevent and cure most of the diseases that kill children. So I think that the creators of "A Private Little War" and any members of the audience who accepted the description of that primitive society as a "Garden of Eden" were very naive and unaware of reality.
