You've completely missed the point of what I was saying and/or are unwilling to see what my point was.

That will only work if you never need to release anything over a weekend... and some of us actually need/want to be able to do that -- safely. As a result we work in a different team structure, with different tooling to mitigate risks and we share the responsibility as best we can (no, not everyone is expected to be 24/7 on call for production).
