The point being made was that informality needs not be specific to the family gathering scenario, and that it's not a core issue of work scenarios at multi-active cultures; I used an example you could relate to illustrate how it could it also be seen at work contexts in some circumstances. So I suppose you downvoted because you didn't get the point.
No, I got the point just fine: at best, there's no reason to apply the "show up whenever" ethos to meetings, because the best reasons for having it don't apply, as revealed by your attempt to come up with a reason. (Unless people are being called to the meeting despite being irrelevant, which is a separate issue.)
