The US dollar has nothing backing it except the full weight and might of State coercion and violence. Look beyond the coercion and violence, and all you see are the printing presses on worthless paper.
What a strange illusion we all live in today that rests solely on the restraint of the State from printing itself out of existence.
At some point there has to be a reckoning in which fiat currencies collectively collapse, and hopefully we go back to the gold standard? Or even better, allow “money” to be commoditized on the free market to prevent abuse inherent in monopolized currencies.
Sometimes ignorance is bliss. . .
