Using banks is way too convenient for people to abandon them. It's like boycotting cars or the Internet or smartphones at this point. And there's really no alternative to them now, not even our beloved crypto, because of fees, transaction times, price volatility, lack of merchant support, weakness to malware and so on. So I can totally see how people who boycott the banks today will return to them in a few weeks once this all blows over.
I do not think that banks have that much importance for our lives as cars, internet or smartphones because there are many alternatives of banking system and majority of people are working without relying on banks but the other three are used by almost all of the people. We cannot resemble these three with banks.
With the current decision of Canadian government not only the victims will lose trust on banks but other people will also worry and will find other alternatives which maybe crypto for them.
