FC, you may very well find the EU banking structure out lasts the EU by a few centuries. It may tank on occasion, but I suspect out of all of Europe, besides the Vatican and a handful of universities, it will outlast most nation states. Just have my doubt about the papered concept of currency, or even a electronic debt… Europe will need actual substance… copper, iron, steel, zinc, etc… for it’s 3-D printers, and assurity it can be held and sent to where it is necessary.
Might not be any difference between a bank and the postal system in 100 years. Industry, like Folded Uranium Plating… stuff that can’t realistically or healthily be produced at home, and the property and hardware that supports it, won’t be generated by such a banking structure though… can a bank or state leverage property, or “tax” a larger municipality or district, if people are largely self sufficient, for they larger, more complex goods that require ever higher degrees of specialization, and harder to produce and acquire components?
I think the FDIC was the first, the Federal Reserve the second, of large regional banking systems designed to manipulate a depot based market of imports and exports on this sort of basis, beyond what the old 18th century imperial systems offered. EU may very likely become indispensable in this regard. I doubt Europe will long last without another EUish structure popping up, seems inevitable, however rotten and in decline this current system is.
Maturity of industrialization will be the driving force that ensures the international banking system for this region survives. No matter what the import or export slate, you need these raw materials in the future… what expedited the digestive tract of Europe the best?
England can survive outside the EU via a commonwealth for some time (not forever), so it needn’t be immediately sucked in. Greece, Spain, Italy, Portugal are at the outskirts, with alternative trade partners, same for Eastern Europe.
My long term forecast isn’t concern for Germany… most countries can print what Germany now makes here in a generation, German technology is a joke outside of hardware. It is seeing how the core can maintain movement of goods between the outer edges, when multiple powers outside are tempting it to be torn apart.
Some unique banking and legal concepts will have to emerge, South America will likely copy whatever Europe does in that regard in mass, without much thought, not to mention the AU. AU is actually fast developing it’s own version of the EU, opening up a universal passport system. Rwanda was the first to abolish passports (honestly, who are they screening to keep out worst than who already lives in Rwanda?)… they got a economic boon from the act.
Lots of countries have been following.
