I don't think this has to be true. Why can't people co-work together, quietly? This used to be the case in libraries, before libraries became places where governments administer social services.
It's nice to work around other people, just as long as they are not on phone calls or taking meetings. These people belong in call centers or meeting rooms, so that people who aren’t talking can continue thinking and working.

After giving up on the open office hot desk, I switched to a private office in WeWork. You could hear the music from the hallway. Furthermore, this particular WeWork was situated on top of a beer garden. Every weekend my "private office" most literally started shaking and vibrating as the beer garden turned into a club. I am not exaggerating. It was a joke.
