I'm guessing his point was that we're so accustomed to relatively comfortable living (especially here on HN), that we take valuable things for granted.
That leads to a sense of entitlement and confusion. We don't see how valuable the things we have are, so we end up thinking they should be "free", without realizing that nothing of value is actually free, because otherwise it wouldn't have value.
So if we experienced real hardship, our thinking would shift, and we'd appreciate valuable things more and we'd feel less entitled.
My point in another, heavily hissy-fit-downvoted message, was that everything of value costs something to produce, and therefore things can't just be handed out for free, because the things themselves are not actually free.
The same applies to "free money" in the form of Basic Income. People like to fantasize about not being personally responsible for their choices in life. Instead, they'd just get free money every month without having to work. "We have the technology!! Why aren't you giving me free stuff?! Damn capitalist oppressors!!"
People should think about how things work in the real world.

Suppose Service X costs you $500 per month to produce. If you keep giving it away for free, you're incurring a loss of $500 per month. That is not sustainable.
In a similar fashion, running the Nanny-Fairy-Machinery and producing things with it would definitely cost something, and that's why giving the output away for free wouldn't be sustainable. It's a Marxism-tinged pipe dream.
