You are speaking like you have seen the future or skme kind of time travel who have seen everything and given us warning about what is coming. When you want to banter other financial system, be realistic and says things that will happen and not just hype things for nothing, this is why some traditional financial markets thinks when we say things, we don't meant but create hype just to favour our investment and once it's pump, we forget everything we said and they are right.
The traditional financial market can collapse because it's controlled by policy and sometimes policy has it limits but what I want to to know is that if banks fail, the government will be there support it and get back fully. It's not like they will let it slide, the government owns the banks and the reason why it can't fail is that they know how to print and once currency are printed, everything comes back to normal, crypto doesn't work like that which makes it unique.
