This is a common retort used by crypto proponents (of which I am one). It overlooks, however, that is it much, much, much easier to do large-scale financial crime using cryptocurrencies than it is to do so with USD due to the intense and robust controls applied to USD for precisely that purpose.

One need only look at the rapid rise of cryptocurrencies in criminal enterprises over the last 10 years or so to see the truth in that.
