As to the boundaries and such, I suspect that you already have it sussed: Bretton Woods & c. (i.e. monetary unions) and assorted mental models and imaginary lines. Private credit vs. lawful money. Is the Federal Reserve System a monetary union internal to the United States? Note that each of the Federal Reserve banks is in a CITY.
Government as in executive departments, as in 'executive agreements' between the executive departments of disparate states? Compacts between territorial bosses? Territorial merger?
The Governments signatory hereto,
...
(1) Each Government pledges itself to employ its full resources, military or economic, against those members of the Tripartite Pact: and its adherents with which such government is at war.
(2) Each Government pledges itself to cooperate with the Governments signatory hereto and not to make a separate armistice or peace with the enemies.[/B]
Consider that the "Catholic-Protestant paradigm" (or is it really a Subject-Born -- Freeborn paradigm?) had Canada in flux: re. Upper Canada (non-Catholic and Protestant, English common law), Lower Canada (Roman Catholic, French civil law) and the Act of Union of 1840 (aka British North America Act of 1840). Consider, what are freeborn sovereigns supposed to do with the natural-born subjects of another sovereign since dissimilar things cannot join together? Rome doesn't want to lose its subjects to other ideologies. Life doesn't want to be swallowed up of the dead. How do the living and the civilly dead get along? Quandry? Is it impolite to wake the dead? There seems to some interesting parallels with: the doctrine of original sin -> born dead / born in debt vs being born innocent. Debt as a transmittable disease seems to be a very much related to a style of doctrine of original sin.
