While I agree this is probably just a made up funny joke, if you you've ever actually lived in a gift/barter community, it's pretty much this. Hung out pretty much exclusively with anarchist and various left-communists for years, and this was my life. You do things for folks, they do things for you, and along the way you end up with stuff like a shit ton of honey, and you end up giving that honey out in exchange for something else, and you end up meeting someone with a weird skill, and it all just spirals into this weird and glorious community.
The difference is that in real life, you're not saying "I'll give you this honey for a bird corpse" you say "hey, man, can I have your bird corpse, I know a girl who loves macabre art, and it would be a really cool way to honor your beloved pet," and then you either give them honey as a thank you, or just later on when it comes up that they want some honey, you give them some because you happen to have some.
I once had a friend who straight up gave this guy his Prius, that same dude ended up giving a mutual friend a place to stay for over a year. Original Prius owner never got anything directly for the Prius, but he was within the little gift economy, and ended up receiving lots of things and services from various members over the years. I doubt he feels like he was not repaid for it.
It's a pretty great way to live. It's a shame we all could never work out a way to get land and built the cohousing community we dreamt of.




I'd argue we do have proper words for 13-19, but don't have proper words for 11&12
