Apart from the obvious reason why it can’t work (jealousy), one problem is that it’s not good for society at large. These groups are probably low fertility for one, and they take partners away from others.
Not to mention that every “polyamorous” society eventually settles into polygamy—-and that’s poison. Expect a reckoning when that happens.
I don't follow, since the group is not a large cohort of society by any means, how can it affect society "at large"?
> These groups are probably low fertility for one, and they take partners away from others.
It might be, it might be not, that's your assumption. "Take" partners away from others in what sense? Their partners might have other partners as well, it's polyamorous after all, I don't understand your reasoning at all.
I don’t understand this statement. Is having multiple spouses (which is what polygamy is — husbands or wives) a poison compared to having multiple lovers?
So no, they're not taking partners from anybody. I don't see how society is harmed if the absolute bottom dregs shack up together instead of staying alone forever.
Whenever I've seen been subjected to photos of a group of polys, the men seem to have a similar look to the one the protagonist had in the closing shot of Old Boy (https://www.youtube.com/watch?v=l0nn-WgLOTY). Certainly their parents do.
Are they representative of the "average poly person," or just one type of person who's prone just go tear down a Chesterton's fence?

You're going to have to be more specific, because that youtube video "...contains content from eOne UGC, who has blocked it in your country on copyright grounds."
