I disagree.

But I will say that it depends on what you mean by fix it. I think the use of violence will be attempted under a bitcoin standard. I also believe it will be proven VERY penalizing for the perpetrator.

Under a bitcoin standard the financial cost for wars is not as easily obfuscated.

Fiat protects the economy in times of crisis, war being a crisis, allowing for wars to last far beyond any ideological justification has degrated beyond public support, since objectives are not ever reached to completion.

Making it expensive is the fix. Its not about suddenly everyone forgets that violence is a thing.. it just makes sure that the incentives for violence are very small compared to peaceful conflict resolution, in the short and long terms.
