They forgot the other, key attribute of a dollar that makes it useful for 'distributing wealth': it has a relatively stable value. Economies rise and fall because of the struggle to control the price of their currencies. The notion that a medium of exchange with no such stability should replace the dollar is bonkers.
Yeah, I'll take a fairly predictable rate of inflation over an inherently deflationary currency with absolutely no controls on its motion. I guess we're supposed to be excited about currency being able to flit around like a panicking moth?
