There have been a number of developments this year that have shown why cryptocurrencies are anything on the scale from useful to completely essential and necessary.
We can start with the Canadian government freezing bank accounts of people that it suspected were part of a protest movement. Whether you agree with this protest or not, if this doesn't make you think that all currency being centralised is problematic, then I don't know what will. And let's remember that Canada is generally viewed as a liberal country.

Secondly we can look at the invasion of Ukraine which recently began. Many Ukrainian people want to leave the country, but if their money is in banks, then they could have a lot of trouble getting hold of it. They might not be able to withdraw from ATMs and their bank cards might not work. People reporting on twitter all of their money in banks is frozen and the only funds they can access is crypto.

Finally let's look from the other side. It is being talked up that Russia is being removed from the international banking system (ie Swift payments etc). If this is succesful then this means that Russian companies will find it very hard to export. I am sure many people in Russia just want to make a living and run their business and don't support an invasion like this. If Russian businesses use crypto then they can continue.
