If the economy is on the brink of collapse, that is when they will try to stop Bitcoin at all cost. Think of Venezuela and all those high inflation countries. They are going all out to stop Bitcoin.
On the other hand, if they think about it clearly then there is a good chance that using bitcoin will save their country from the brink of failing because of the inflation rate. There is no other way to save the country from high inflation instead of using other currency which obviously using bitcoin is the best for this case
