To many things happened in 2 decades :
Terrorists attacks / Wars on Terror / Arab spring / SARS / Climate Change / Covid / Global trade problems and so on ...
Before 2001 life was normal ...does how are older remember ... now they are not even hidding it / no longer in the shadows what they are trying to do ...
Is it just to take peoples freedom for the "greater good" ? Will people allow their freedom to be taken ?
I don't think that banks are going to die in the next few years. It's been 20 years since 2001 and many bad things happened, but so did it in the time before. Maybe there were less terror attacks before 2001, but there were other bad things like wars too. I don't really understand how banks are being the problem here. Without banks all the things would have happened as well. Saying that it's the banks fault for us losing our freedom is wrong in my opinion. Most of us already gave up their freedom by using all the social media in todays world. The big companies are getting all our personal information for free. Who knows how much of our pictures and messages are being stored on some servers.
Those are different kind of freedoms, the right of privacy has been basically given away for free by the majority of the population simply by the promise they could get their own 15 minutes of fame, and people are happy with that.
Banks are responsible of taking a great deal of our economic freedoms away, for example the things we can do with our cash are more and more limited and it is obvious they want to introduce all kind of similar regulations to bitcoin, I think they will fail but that does not mean I think banks will disappear in such a short amount of time either.
