> It's fascinating how people assign value to an asset created out of nothing that will never show revenue.

The USD is created out of nothing currently and does not show revenue (if anything, the US government only creates massive debts that will have to be paid in the future thru massive taxes hikes, or inflation, or both). The only reason why the USD has any value is because it's the single piece of paper that is authorized as a currency in the US, and that people 'trust' it somehow (especially outside of the US). The day the trust is gone, it will be worth absolutely nothing.
