The technical aspects of your argument may or may not be a hinderance, but most people would never get to that point because of the world wide poverty that exists for almost every country outside of Westernized developed countries. The goal for poverty stricken citizens is not to adopt a new currency or to invest for future wealth. Their vision does not extend that far. They live each day trying to get enough resources to have enough to eat.

Bitcoin isn't suppose to take people out of extreme poverty nor would it matter if the extremely impoverished adopted crypto. There isn't a large amount of wealth controlled by these folks. World wide adoption really only includes the major players, US + EU and China.
