problem seems to be [...] intertwined language with culture
You lost the argument right here. Language is as fundamental to culture as the sky is blue.
The rest of your post amounts to "communication is important to function" and you are not wrong on that front. But you put no weight on the importance of culture too.
Consider this your wakeup call, that just because you don't personally care about society having an identity doesn't mean the rest of us don't.
You are not wrong about the lack of corporate culture. But at the end of the day, is that worth giving up family time, company of your pets, a corner office of your choosing, with access to your own fridge and amenities, being able to receive people at the door at reasonable hours, and not having to commute asinine hours?
Many people will reject that notion.
But here's the kicker: companies don't care about your well being. They only care about the bottom line. What incentive do they have to cater to your needs? None, other than the minimum for employee retention.
This idea of "team building" is just smoke and mirrors. An excuse to not have to admit the real reason: adapting away from buts-in-seats as a performance measure is hard.
