Every business needs millions, if not billions, of people working for them. The complexity cannot be handled otherwise.

But back to the topic at hand, there is an impossible level of communication overhead to burden if you try to keep millions (or even tens) of people on a single team. Like the original comment pointed out, we've never actually figured out how to do that. It might be a good idea in theory, but the problems remain unsolved.

The workaround is easy, though: Just don't do it. Do what everyone else does instead.

Yes, I've tried to point out a different problem with your scheme. Outside of hypothesis, we do have a global market - I think it's disrupting your idea because you cannot prevent an independent team to enter it.
