Counterpoint: there are types which really like to insert themselves in every conversation or discussion. To the point it hampers not just their own work, but the work of everyone else. Taken to the extreme, they even create a state of helplessness in others, where these individuals become a funnel for all others to ask questions and obtain knowledge from. This is without accounting for all the noise pollution it creates.
Opponents are very eager to pull out these 'what about the office talks?' arguments, but whether the benefits even outweigh the downsides isn't obvious at all.
Heck, most developer work cultures use Scrum, and they can't even work through a single item on their retrospectives. Surely a bit of skepticism is warranted.
