What do you actually want Western nations to ban? The purchase and sale of digital currencies?? What if a nation adopts Bitcoin as its national currency? You can no longer buy and sell another nation's currency? What if you want to visit that country? (The what ifs will not end at these few examples.) I don't clearly see what you would actually propose banning. My opinion is it's technology, an idea, and that shouldn't be banned.
