This impacts mostly exchange rates and those who engage in foreign trade.

My point is nobody I know uses USD as a currency to save, transact and measure value.

Besides, the devaluation of the Rupee in India has more to do with the actions of the Indian govt than a foreign entity. Debt issuance, deficit spending, lowering of benchmark interest rates by RBI, stimulatory monetary policy play bigger roles than what the US did. Forex is a factor, sure. But one of many.
