"Government are unaware of people using bitcoin or maybe aware but has not taking actions in this to avoid making some losses especially in terms of the asset that determine the value of the economy represented by fiat currency" as at this day this is no longer valid because many government authorities are taking action against it. And why will I need to travel with a huge sum of money am I not afraid of my own safety and even with how the way is going cashless. I don't see any point to which bitcoin could destroy the economy from all your stances.
