I was originally addressing this comment form OP. Below for your convenience.
> > If you actually printed money, which does not have interest to be repaid, then the amount of circulating money would've increased permanently. Therefore, the expectation is that each printed dollar is worth less.
So I really do not understand the relevance of what you are saying. It seems disconnected from the actual comments I made. I did not mention "necessary". I think you might be responding to the wrong thread,
I am responding to this "So If when the dollar goes up the US prints more dollars, are they really getting into debt?" - which I think can be misunderstood.
OP said printing dollars makes the dollar worth less
> expectation is that each printed dollar is worth less
And I said in times of instability the demand for dollars increases (dollar goes up).
What I am saying is the "every dollar is worth less" of printing dollars might be offset by the higher demand of dollars in times of crisis.
