You seem to forget about China, last year President Xi Jinping announced he would issue their cryptocurrency this year, but don't know yet what month it will be realized. and one more country that is rumored to be starting to use digital money that is Malaysia, cmiiw
Let them do what they want. If it is good for their country to prosper even more or to have more convenience than before then it is a good decision for them to test digital assets for their economy. If they will have a positive result from this experimentation then we all know that most of the developing countries will do the same and they will immediately use blockchain technology.
