There are over 8 billion people in the world and 195 countries. Not everyone will lose trust and confidence in central banks no matter how bad it becomes. Not all governments as well would deteriorate even if it seems that way.

Like you said total domination of bitcoin is not gonna happen soon but as everyone slowly realizes the potential of bitcoin let us take advantage of it.
