There are more factors at play than just math. Trust is one: The value will be where people think it is. As an example, if Germany announced to leave the Euro and start over with a new Deutschmark on Friday, the bottom would likely fall out of the Euro and the new Deutschmark would go through the roof (if the German gov't would fairly exchange every last cent w/o screwing people over).

In that respect, value can be "hardforked" or "printed", if only enough people go along with the concept. It is the basis of every modern fiat currency. The disconnect between real value and currency is clouded over by the massive real value people see all around them (in developed nations) and the values they can buy every day.

This fork might well be a great new start. One can hope.
