The meeting might be 1 minute shorter, but the 50 minutes of time that one confused person lost when they stopped following for the rest of the meeting is also a waste, as well as the 10 minutes of time it takes the one person they pull aside to catch them up afterwards.

No - 50 minutes a junior spends trying to solve stuff on his own is 50 minutes invested in being more independent I consider that an overall gain.

I would take a junior that comes late with his tasks but mostly works independently over a guy that's asking the rest of the team for every setback so he can deliver the stuff he promised any day of the week. Juniors are almost always a net negative for the team - the ones who know how to reduce that are a huge benefit.

That might be true for independent development work but not for meetings, which was your original point
