Gutting the state by taking away their ability to print money (a lot of it used to surveil) is a main benefit of money going back to a neutral form.
I love the idea of no fiat currency exchange rate arbitrage. So many people globally would be freed from the shackles of strong money enslaving improvised people beholden to weak money. Billions under weak currencies would be free to provide value and get compensated on a level playing field.
