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.
There are people that depends too much on bank's but there are also people that can still live peacefully without a bank. Cryptos have that disadvantage you mentioned about but let's not forget that cryptos do also have an advantage and most importantly they are not tied to banks so no bank restriction that's going to happen.
This main functionality of crypto is very much needed now in the on going issue with banks and governments in Canada. I cannot believe how the issue in that country grows and spread like a wildfire because we thought it is just a simple issue that can be resolve immediately but I guess no. Let see how far this things go.
