This is a good point. "Net worth" frequently isn't even liquid, but moreover, it's also completely subject to the whims of the government that controls that currency. That government is able to enforce its whims using sheer force, through its military. NK may not have that much worth in USD, but it occupies territory and has military force to back its claim, and that military is motivated by things other than USD numbers on computers somewhere.
