No.
Monetary policy only has to be tied to fiscal policy (for the country with the 'reserve currency) if there are other countries with stronger balance sheets and an economy sufficiently large enough to absorb the demands
of the world for currency to trade.
At the moment, the entire world is in or headed towards fiscal calamity. That makes our position, vis a vis printing money, not only viable but expedient. I'm not advocating that course of action, but this is an economic discussion.
Once the rest of the world goes boom, we go boom.
I don't think I disagree with you what you're saying depending on how you're using the word expedient. Since you're not advocating the policy, I presume you mean that it's just promoting a short term objective without regarding the long term consequence.
And it also leaves out the option of a country or cartel switching back to a gold standard or currency backed by precious metals or some other commodity. I think there was some discussion of Dubai going over to the gold standard with their currency a couple years ago.
I think it's critical that everyone viewing current events realize things aren't static. Everything that we've come to accept as permanent is subject to changing and correcting itself. We're going to go through a period of great change and we need to be on the right side of history, we need to get our affairs in order, and maintain our independence from the pit the rest of the world is going to sink into- in order to avoid the "boom" you refer to.
