Whether or not the electronic money through the future is easy is a difficult question. Firstly, in terms of economic integration, this is very difficult now because each country has its own face value and money, it is difficult to synchronize, another difficulty is that the legal is unclear because each country has one private law. Secondly, the political, military, and information technology are uneven, leading to access to electronic money is not virtual reality. So how to solve this problem?
That's is real even now bitcoin and the whole virtual crypto currency is harder to accept by other because of many reason like you said. But I still believe all prolem have a solution .
Your just making things worst,first bitcoin will never replace those currency that you are mentioning so whats the problem being bothered by this?all the existing fiat will remain so there is a plenty of things that can be used bitcoin.Japan is a well develop country and we know how strong their Yen is,but did they bother to made issue for crypt?ofcourse not because what they did is accept and adopt this technological currency to their economy

Well" you had a point but sooner bitcoin is the most important thing than fiat money in the future and I believe until the new technology going to growing up including bitcoin because is part of the new technology.
