Excellent example and yes I agree that is an amazing system- however is it only able to exist because Switzerland has for centuries been the designated neutral 'vault' for Europes warring nations?

It seems like Switzerlands unique and beautiful system is perhaps only viable because they have acted in that role of agreed neutral 'store of value'.

Switzerland is the exception that proves the rule...because Switzeraland has avoided the need to compete militarily with its neighbours, that has saved huge centralised investment and thereby enabled considerable private wealth and freedoms not ordinarily possible in most nation states.
