I think quite the opposite — Geopolitics is impacted all the time by your actions. What you buy, what you say on forums like HN (where potentially tens of thousands read your comment), how you educate your kids, how many kids you have, how you influence co-workers.
The reality, is the world is smaller than you think. What’s the phrase, “everyone with 6 connections away from anyone else”. If you can have a major or even minor impact in your local region of the graph, it’ll expand outward.
I’m a cynical person by nature; but my cynicism comes from the lack of action / belief in action around me. You and everyone you know can really change the world in some way, if you push out your ideas and product(s) (like you are here btw, I’m not trying to claim you don’t)
That said, I always focus locally to build the community I want to see. It influences geopolitics, but that starts at the coffee shop, book store, school, home, etc.
