Hi good job, but the title should be broader.
If you want to criticise fiat money, why not point out all that is in contradiction with islam:
1 interest: every fiat money is born out of lending with interest.
2 measures and weights: by inflating the money supply the measure of mobey is manipulated.
Ad 1. No comment, as this is the subject of the book.
Ad 2. This is a way bigger issue then interest. As manipulating measures and weights is equal to stealing. Creating fiat money out of 'nothing' inflates the money supply. As money is a measure for price, inflating the money supply distorts this measurement as opposed to sound money systems (gold, bitcoin). Purchasing power of savers is tranferred to borrrowers. Although borrowers have an advantage, ultimately everyone becomes a (debt) slave to the fiat money system.
A lot to say but i will stop here.
