@Cognitivedissonance it's not currency that means anything it's products and goods that mean something. You can have 1 million dollars but if it only purchases you a 'loaf of bread' then that is worthless.
Currency is valued on what it can buy you. In your thinking 'gold' is useless also since it can be argued it's just a 'piece of metal' but what makes it valuable is because it's rare and the other reason is 'consensus' in the market place that it's desirable. If it wasn't for those 'two factors the rareness and consensus' gold would be treated not a currency in the past.
The reason they chose 'gold' was they could control it thru who can 'mine, extract, and mint' it thru a 'treasury'.
They do the same with the 'dollar or other currency' ensuring it's 'rare' and no-one else can print it and it also has worldwide consensus. It will remain a currency, as long as it's rare and has consnsus of the people and there is no other currency used in the market.
A GDP isn't about how much 'currency' you have u dumb prick, it's about how much goods/products/services your average citizen consumes. GDP is about consumption levels because consumption levels lead to production levels. Currency is only used as the 'transaction' what is desired in a GDP isn't more money but 'more products and good consumption' and that comes thru jobs. Thru more products and good consumption, it leads to more production and suppliers and over-all wealth.
A western person is consuming in a given year far more then the average Somali, that is why the two people are poor or rich not because of currency or fiat or whatever garbage u sell yourself. An average westerner spends $100 a week per person on food consumption.
While the average Somali household spends $50 a week, that is a household waryaa.of an average of 6 people. Nigga u have the purchasing power of 12 Somalis per 1 westerner. That is why the two are considered wealthy or poor.
