If Sweden can be able to do this, I believe it is not all other countries as you have put it that can follow suit, because many countries are still fall short of technologically and electronically know how. So, its damn not going to be an easy journey for them at all and even, most of them still believe though ignorantly in Fiat currencies for real other than any Cryptocurrency.
Only a few % of countries are now remaining which are not having the facility of new technologies, every country I know is highly accepting bitcoin, it is the electronic age and it is need of the day to have such facilities in your life so that you will be able to make, some ignorant courtiers [not ignorant actually but they are lack of information and knowledge] are in fiat so they should accept the past with regret and accept the present with confidence and get bright future with bitcoin without any fear of lose.
. As you said, are Chinese government stupid? Because the speed of growth in technology of this country is one of the fastest countries on the world.
