I think people are simply too little "social" (in the real world sense) for open society: modern societies tend to concentrate people to a point of starting some real-life human variant of an old experiment https://en.wikipedia.org/wiki/Behavioral_sink https://en.wikipedia.org/wiki/Behavioral_sink and that's why we see many flawed, tribal behaviors IMO. Aside I suspect that most people are unable to know/understand the purpose of a society, why we do anything, so they do their best to avoid any change and anyone who is "different" as a way to "remain on the right track". However this seems to be always the case at least in large part of known human history and in the past we have had many open societies so such behavior while presenting many social issue should not be a showstopper for an open society anyway.
