I see your point, but its hard to be in a circular economy, even in countries like Argentina. You do not have the need to interact with USDT like we do, alway changing in the black market, with this shitty coins, peso in my case. Certanly the necessity will drive the speed of adoption, but we are so far away. 

The only thing I could think of is a total and catastrophic collapse of the dollar. Otherwise, It will a slow death for all.
