If the control of money can cause a war, then surely a neutral money can end the emergence of such kind of war.
Bitcoin replaces the need for coercive force; armies, and laws with mathematical trust.
Can Bitcoin be a tool to replace violence?
Zoom out, this is all it takes to see that many past wars doesn't start simy because of money, greed in other country's resources is far more acceptable by me because it is something that have caused war in Africa, another one is hate.
We humans are never satisfied that's why the Bible says that any man that is contented has everything, it is very rare to see humans who are satisfied with all they have and not want more.
Bitcoin has nothing to do with world resources, Bitcoin is neutral, it stands alone, Gold mines exists in many countries, some have oil and vast lands and many earthly precious stones, what can Bitcoin do about this? Nothing, even if Bitcoin become the #1 most valuable in the future, it doesn't mean that other earthy resources are useless, Gold for example can never become useless.
Many other things are been used for producing what humans consumes, they won't stop using them and the value will always be there, wars and other adversity is part of the world we live in, nothing can erase it completely.
