Once again, this is something I hear often and I strongly disagree. I'm lucky to be born into western civilization with the paradigm to respect the power of an individual. It seems to me it is eastern influence to speak in this dismissive way about individual actions. "No one is irreplaceable" is another common phrase. Someone says he decides to leave a community, and there's inevitably someone saying "goodbye!" with some equivalent of a mocking smirk.

I'm also lucky to have affected stuff myself in the past, e.g. I caused local government (~10 000 residents) to change. Actions of an individual very often do matter. It's just unfortunate we often don't get any feedback for our actions and it seems like they don't matter which demotivates people from any form of activism and puts them in this depressive, hopeless state of mind. Imagine how beautiful the world would have been if you had some kind of a debugging tool to inspect how your actions affected others, with a side by side comparison of your universe and some alternative universe where you haven't taken an action. This is also why I try to give feedback to people, send thanks to authors of free libraries etc.

Do you think the French revolution happened in isolation?

I don't necessarily agree with the OPs approach. He could have filed a complaint or done any number of things that may have been better. But in the heat of the moment nobody is making perfectly rational decisions.

Regardless, we need to fight back against abusive systems on the big and on the small. We won't always get it right but the act of fighting is what matters.

It's not flawed at all. If the last five years have taught ideologues at Disney and in the video game industry anything, it's that you can waste hundreds of millions on ideology-drenched projects and get, say, 1000 concurrent players as your peak.
