A Grexit would force these rules to be defined, therefore making it clear what a euro is worth, depending on where it is held, by whom, and in what form. Indeed this would not only make the break-up risk more imaginable; it would also make it much more concrete.
最后，退出将迫使欧洲决策者将目前尚未成文甚至尚未具体化的“离婚规则”正式化。除了国际法的宽泛原则——比如，对决定一项资产的分离后货币计价来说，重要的是基本合约的约束法律和相应的司法辖区——没有一致同意的规则约束如何实现新货币的转换。希腊退出将迫使制定这些规则，从而明确地表明，某欧元价值几何取决于在哪里持有、被谁持有、以何种形式持有。事实上，这不但将让解体风险变得容易想象；还会让它更加具体化。
