Unless the war is popular. It can still totally fund popular wars.

It just stops the government from financing wars agains the wishes of the population.

The more I learn about fiat the more I wonder how anyone spends their life working for it for any reason than to break free from it. No doubt it’s okay to have some, but I wouldn’t consider it a good store of value. Get fiat out of your hands as soon as possible. Buy goods, bitcoin, or produce a service. Supporting fiat is supporting war.
