You mean you're not actually supposed to spend 2 hours daily unfucking everyone's shit during the standup turn by turn?

My team does this for the first ~15 minutes and then we move to "group think" for any tough problems or "water cooler chat" for the remaining 15. You're allowed to leave if it's just water cooler chat, so I really like it

Problem is in practice, I suspect something is pretty wrong in most teams.

Some common examples come to my mind:

• Management hears "talk about what you've done and what you will do" so great time to sit in and take notes for performance review, and it becomes a "make sure management knows you spent all your time and did really impressive stuff" meeting. Also throws a kink in "things I need help with" as there's always the risk that management decides you aren't self sufficient enough if they hear you got stuck, so you also need to defend why you got stuck and how it isn't your fault.
• The people who feel like everyone needs to know the minutia of their trials and tribulations including all the intermediate dead ends they went down on the way to their final result. Related to the above, but there are people who think to do this even without the need to impress management.
• The people who cannot stand to "take it offline" and will stop everything to fully work a problem while everyone is still ostensibly supposed to stay in the meeting despite having nothing to do with the two people talking (sometimes even just one, a guy starts talking to himself as he tries to do something live).
• Groups that are organized but have very little common ground. An "everything must be scrum" company sticks a guy who does stuff like shipping and receiving into a development team and there's no 'scrum-like' interaction to be had and yet, there he is wasting his time and having to talk about stuff no one else on that meeting has a need to hear either.
