The tenor of my post was related to the fact that in a large organization, anyone, from anywhere can send you email, cc you on email, forward you email, reply to all on every email, or just about anything else; whether you want them to, whether you asked them not to, etc.

The poster's assertion that it's just a "human problem" and tell people not to send you irrelevant emails is incredibly simplistic; for example some of those "irrelevant" emails come from my bosses'

I can control how I choose to handle email and even to some degree I have some ability to influence the behaviors for my direct staff, but beyond that? Not so much...
