I tried to have fun with Twitter's Periscope a year ago, which has been out for a while. It's a group video chat app where anyone can pop in. In that way it's sort of like clubhouse, but with video. When I would get on, it was 80% people sitting around talking to their friends, often in thick accents about nothing of particular interest (e.g people I don't know, things the chat participants experienced together that I have insufficient context to understand). That's probably 95% of the internet voice and video chats and I'm just not aware of it because I'm not randomly dropping in on people's conversations like you're allowed to do on periscope. Anyway, it's not the most easily monetizable thing, I'd imagine.

On Telegram voice chat, there's always some jerk or lunatic who talks over everyone who the rest of the chat participants have to tell to shut up. I think this is just a telegram problem because clubhouse has better moderation features.

Anyway, if you have a group of people you know and want to talk why not use Zoom? It's a better experience in every way. What's the benefit of letting random people drop in? Maybe with very clever moderation features it could work, but as is it seems kind of pointless.
