At which point, you might as well be in a physical meeting. You're either synchronously communicating (and not paying attention to something else) or you're not.
Except a physical meeting involves getting up from your desk, going somewhere, waiting around for everybody else to get there, having whatever meeting you're supposed to be having, hopefully without anyone taking it off the rails into some unrelated tangent, winding down the meeting, then going back to your desk. There's a lot of wasted time there, and I get very irritated by other people wasting my time.
Then there's the fact that nobody ever records the audio of in-person meetings, and almost never actually takes minutes or notes of what was decided, so the only record of it is the progressively hazy memories of the participants. So then you have another meeting next week to rehash the shit you just went over.
I agree completely that these are people problems.
I have a huge preference for technical solutions that do the right thing by default, rather than trying to get people to do their jobs right. Most people are aggressively mediocre and don't seem to have any impulse to do their jobs in the most efficient way. So I can either get on their ass and chaff them along all the time to do things right, or you can use tools that make doing the right thing easier than not doing the right thing.
