I think it's mostly emergent. I can even point to a plausible mechanism, which is that if you think of an organization as a network of people and how they are connected together, you can think of "responsibility" as something that arcs through an organization like electricity and burns out whatever it courses through, prompting the creation of alternatives to avoid getting zapped the same way in the future.

It isn't completely inevitable, I think it's possible for relatively strong leadership to understand that the processing of responsibility through an organization is a necessary feature and people handling it without external forces conspiring to make it even more like that it will "burn out" a part of the org is a necessity and a good thing. But it's really easy for an organization to just default to burning out the path and evolving ways to avoid it in the future, and it is very motivated to make it happen.
