Which... means everyone's read it?

Might consider a spoiler warning.

Maybe "peace" is meaningless without humans to observe it?

So is world peace. People are all flawed and there's no escaping it.

This is logically incoherent. It's just saying that we'll ignore all the reasons world peace is impossible because they're part of the world not being peaceful. We could just as well say that it's possible for humans to fly by flapping their wings - all the reasons why it's impossible are part of humans not flying.
