Are you saying that the good thing about fiat currency is that the gov't can use it to finance a war? Because that's one of my main complaints about fiat currency.

Whatever you pay your taxes in will be used to finance a war.

For your statement to be true, I would have expected a big rise in my taxes over the last decade, and perhaps a corresponding contraction of other gov't spending. I've seen neither, nor do I think the gov't was hoarding a big war-chest of funds for such an occasion. The main point of my comment was to point out that when it's possible for the gov't to finance war(s) with deficit spending as opposed to war-bonds, people freely ignore it, as you've demonstrated.
