My referent for 'heroic responsibility' was HPMoR, in which Harry doesn't trust anyone to do a competent job - not even someone like McGonagall, whose intelligence, rationality, and good intentions he had firsthand knowledge of on literally their second meeting. I don't know the full context, but unless McGonagall had her brain surgically removed sometime between Chapter 6 and Chapter 75, he could actually tell her everything that he knew that gave him reason to be concerned about the continued good behavior of the bullies in question, and then tell her if those bullies attempted to evade her supervision. And, in the real world, that would be a perfect example of comparative advantage and opportunity cost in action: Harry is a lot better at high-stakes social and magical shenanigans relative to student discipline than McGonagall is, so for her to expend her resources on the latter while he expends his on the former would produce a better overall outcome by simple economics. (Not to mention that Harry should face far worse consequences if he screws up than McGonagall would - even if he has his status as Savior of the Wizarding World to protect him.) (Also, leaving aside whether his plans would actually work.)
I am advocating for people to take the initiative when they can do good without permission. Others in the thread have given good examples of this. But you can't solve all the problems you touch, and you'll drive yourself crazy if you blame yourself every time you "could have" prevented something that no-one should expect you to have. There are no rational limits to heroic responsibility. It is impossible to fulfill the requirements of heroic responsibility. What you need is the serenity to accept the things you cannot change, the courage to change the things you can, and the wisdom to know the difference.
Did we read the same story? Harry has lots of evidence that McGonagall isn't in fact trustworthy and in large-part it's because she doesn't fully accept heroic responsibility and is too willing to uncritically delegate responsibility to others.
I also vaguely remember your point being addressed in HPMoR. I certainly wouldn't guess that Harry wouldn't understand that "there are no rational limits to heroic responsibility". It certainly matters for doing the most good as a creature that can't psychologically handle unlimited 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.
