But it gets even better. Since there isn't more BTC in this physical place or in that, it shouldn't lead to the terrible sufferings of colonization and war. Like, people can't get together and decide to violently take over a country (like the Boer and British settlers did in South Africa) to start exploiting the resources (including diamonds and gold) there. And no one can decide to violently remove a people from their ancestral and sacred lands (like the US government did to the Lakota in the Black Hills of South Dakota) to extract gold from them.
Never underestimate the nastiness people are capable of. All you are protecting is a private key, which I'm sure could be extracted from you by some real nefarious methods...
Plus there are still tangible resources other than bitcoin that people will always fight over, and we haven't even discussed religion yet!
Bitcoin is pretty damn cool, but not WW3 stopping if it came to that
