Why not? Congress is meant to be a check on the other branches of government (though the filibuster rule / partisan omnibus bill system has degraded its collective will, which is why they won't do anything), so pre-emptively removing the powers of congress from the list sounds like a power grab. It's not like it's something completely irrelevant. Same for the limitations of government listed there.

Besides, the thing about organizations is that they encourage behaviors. A big corporation encourages different behaviors than a startup, and different company cultures can also encourage / optimize for different things. There's also a reason why we do expect ultimate responsibility to rest with leaders.
