I don’t agree with this.

If you’re in a place that wants dollars or euros because their currency is “bad” (volatile or unable to freely exchange for dollars), they prefer dollars. You can tell because you get a better than official exchange rate.

I have to say I’ve never been somewhere that the currency was so volatile the settlement date mattered. Carrying local currency would be part of your risk? This could only come up in the almost-all-digital-currency modern world.
