Look that's why I said "if that money ever get paid off" not "when it gets paid off". And of course the only "not extremely bad" alternative is to continually roll over public debts forever. Financing tricks though don't change the value of the underlying assets, which is really the point that I'm making. I don't disagree at all with what you're saying.
The problem is that eventually the debts can grow so large that the people who are expected to service the ever increasing principal and interest payments view the debts and overwhelming and/or odious, and choose to default. Then you get a deflationary spiral (i.e., Greece, Cyprus, etc), or alternatively currencies can hyperinflate to service the debt, which is essentially another form of default (i.e., Japan).
We haven't really seen the current situation before, so don't know how this plays out... but we'll find out soon enough I think.
