Those who have read up on decision theory will be familiar with the term superrationality and notice that you are misusing the term.
Superrationality involves assuming that other people using the same reasoning as yourself will produce the same result as yourself, and so you need to decide what is best to do assuming everyone like yourself does it too. That does indeed seem to be what eli is talking about: you support the existing system, knowing that if you think it's a good idea to support the system, so will other people who think like you, and the system will work.
You seem to be confused either about which piece of literature is being discussed or about the target audience of said piece of literature.
I don't think he's confused. While Eliezer's fanfic isn't children's literature, the fact that Harry is a hero with plot armor is not something Eliezer invented; rather, it carries over from the source which is children's literature.

Recursive Heroic Responsibility
Heroic responsibility for average humans under average conditions
I can predict at least one thing that people will say in the comments, because I've heard it hundreds of times–that Swimmer963 is a clear example of someone who should leave nursing, take the meta-level responsibility, and do something higher impact for the usual. Because she's smart. Because she's rational. Whatever.
Fine. This post isn't about me. Whether I like it or not, the concept of heroic responsibility is now a part of my value system, and I probably am going to leave nursing.
But what about the other nurses on my unit, the ones who are competent and motivated and curious and really care? Would familiarity with the concept of heroic responsibility help or hinder them in their work? Honestly, I predict that they would feel alienated, that they would assume I held a low opinion of them (which I don't, and I really don't want them to think that I do), and that they would flinch away and go back to the things that they were doing anyway, the role where they were comfortable–or that, if they did accept it, it would cause them to burn out. So as a consequentialist, I'm not going to tell them.
And yeah, that bothers me. Because I'm not a special snowflake. Because I want to live in a world where rationality helps everyone. Because I feel like the reason they would react that was isn't because of anything about them as people, or because heroic responsibility is a bad thing, but because I'm not able to communicate to them what I mean. Maybe stupid reasons. Still bothers me.
