You don't have to wait for such an extreme event to happen to see some impact or disruption of the status quo. After all, it is simply wishful thinking to consider it possible that the majority of the world's population will suddenly convert all their fiat into Bitcoin. That's not going to happen. But the disruption is there. Remittances in some countries, for example, are done in Bitcoin. Some people have also quit saving in fiat and shifted to Bitcoin instead. I mean, there are small yet significant disruptions happening right now. There's no need to see shocking events just to see the impact of Bitcoin.
