The context was "business", that kind of application is developed quite differently than, say, a cool little hobby terminal emulator or whatever.
Even though the business currently doesn't have a need to e.g. support any other currency than USD and EUR, an experienced developer will clearly see that it is unlikely to stay that way for long, so doing some preliminary preparation for generalizing currencies may well worth the time.

Your regular business requirements are way more complex than just a currency list. This is like trying to justify your point using an oversimplified example imo.
