It's funny that his TotC paper is often taken as an argument, based on a misguided economism, that privatization will solve common pool resource problems. Economists are the great villains of this book, telling ppl not to worry about eco problems and thus leading us to disaster
He's very much in the "you can't eat money" "economics is nonsense made up to perpetuate the status quo" school of econ criticism here
After shitting on externalities in the last chapter he's now completely embraced the framework lol. Anyway here's the poison pill: embrace reproductive coercion and you'll never have to worry about the environment again
He is arguing that Oedipalism is the principle cause of imperfect replication in cultural evolution??
Here he's making fun of the idea that you could privatize your way out of the Tragedy of the Commons. He thinks market incentives work perfectly well when property rights are enforceable but considers that absurd for most environmental problems. V much not a libertarian!
Technology has reached diminishing returns, "Progress" is over, and there are no human needs not already met by the devices that existed in the 1960s. Definitely at least a bit of primitivist energy here (which is good; he'll need that for his world of drastically reduced pop!)
Btw the sci-fi conceit is that the US built a doomed colony ship and launched it into space as an intentionally wasteful megaproject. The ship has two parallel societies. One is free to breed, die, and adapt; the others are biologically immortal and sterile, to preserve culture
The immortal ones watch the others, who don't know they exist. The immortals will decide who colonizes the planets they find. What no one in board realizes is that they were never meant to find other habitable planets in the first place.
I feel like I should be putting like a content warning on this blatant white supremacist propaganda or something. Jfc
Here's where Hardin makes his big technical mistake: by ignoring benefits of fertility, he short-circuits the demographic transition. He mistakes the eventual, speculative outcome (selection for fertility) for the present race and class divide
He has either negligently or maliciously set the whole process backwards in order to arrive at a backwards solution (make people poorer so they have fewer children)
Hardin weighs a proposal to "cap and trade" reproductive rights but rejects it because it allows too much choice (his logic on this is not quite clear)
Hardin pretends to take his opponents' position and come up with an alternative to coercive sterilization of women. His answer, somehow, is to make up a technology that allows us to decide the sex of a fetus. Women can have as many boys as they want but only one girl.
As it turns out, this preemptive femicide is actually feminist! It makes women a scarce and therefore valuable commodity. He expects this to result in a polyandrous, matriarchal society. Feminists are just too dumb to realize this.
So the whole reason I tracked this down in the first place was to fact check a quote about it from a secondary source, which worked very nicely in my essay. As it turns out, apparently like everything in this stupid debate, that quote was in fact a misreading of the text

The parable in the book is all about what happens on the ship itself. They receive some ominous but inconclusive communications from Earth, then show up there 5000 years later but the book never says what they find. Not Wall-E after all
