If you're working in a largely co-located company, where video conferences are an uncommon occurrence then this probably fits.
In the context of this conversation around remote only companies though, everyone is going to be set up to be able to properly participate in a video call - that means making sure everyone has a decent internet connection, microphone, and camera at home. When people aren't at home tools like Zoom have the ability for them to dial in to conferences on a regular phone which deals with the remaining problems.

I've worked mostly remote for many years and please trust me - it's almost exactly the same, with every weekly meeting starting with "is everyone here", "do you hear me?" etc etc.
This is especially when working from home - typical residential connections are having less nicer SLA and may get flaky from time to time. And someone may leave their phone near mic cable. Or someone's machine may need rebooting. Or conferencing service may be experiencing problems.
Glad if it's not like this for some, but I believe it's not exactly uncommon.
I worked with a team remotely for 3 years, solely relying on Google Hangouts for video and an occasional Zoom meeting. The video/mic/hardware problems are _incredibly_ rare.
Being late or grabbing coffee instead of starting a meeting are culture problems at a company, not problems with the medium.

You've had better luck than I have. Our New York team is still dealing with the problem of the Boston office being virtually inaudible, while Dublin sounds like they're speaking through a megaphone directly into my ear.
That is, assuming we didn't lose a room, or the Hangouts equipment isn't broken - then Boston uses our manager's laptop, which actually sometimes has better sound quality.
I covered part of this under "being available" at the end of my comment. But I completely get what you're driving at. Apart from people's availability, some of the technology is still horrible and quite unreliable (I'm looking at you, Skype for Business). But my main point was that writing emails and documentation cannot be a substitute for instant communication (chat) or voice communication.
"Ok, we're all here. Wait, where's Mike?"
"I think he was making coffee. Let's wait for him."
"Hey, is Zhang saying something?"
"Zhang, say something."
"..."
"I think your microphone is broken."
"Can you disconnect and reconnect?"
"Hey, he's typing something. I... will... reboot. Ok, let's wait for him to reboot."
"Hey, Mike's back. Someone tell him we're waiting on Zhang to reboot."
"I don't think he can hear us."
"Guys, I'm gonna go grab a coffee while Mike and Zhang figure it out."
