It also does without it's star players which is what I mean. A company needs a lot of people, but has a pool of star players who are redundant only on paper. If they really drop away, it's a massive issue. And if they drop away all at the same time, the company will stall or worse depending on size and cash position.

Ofcourse the large enterprises have (ISO etc) processes in place to make everything as process-driven as possible, but you can see that even in teams within MS / Google / Facebook there are superstars who are simply very hard to replace (and in these companies they are well compensated; but outside tech that might not be the case). Obviously it never happens that they leave all at the same time, so that's why it looks redundant.
