Because with the actual geopolitics we could easily see a few other countries seeking to avoid The US. And I don't mean only the US sanctions (or the potential ones), but the dollar system (when it's about international trades) I was thinking about Iran, Russia, China, but the list could grow up quickly. Why do you think we see some countries claiming they will create their countrycoin?
Most coins aren't private so what? Aren't there privacy-centric cryptocurrencies around there? Do they really need to use privacy coin?
I don't think there's anything special in them saying that they want to create a countrycoin, before crypto there were similar talks about digital currency, and before that there were talks about gold-backed currencies. Yet here we are, decades later there's still no new currencies. I think it's because that all was just a populism rhetoric for boosting morale at home.

Bypassing sanctions would mean that western companies would have to break the law by doing business with sanctioned countries, and you need privacy for that. But it would be impossible to do on a large scale anyway, you just can't cover it up, so crypto won't solve anything here.
