They are of the point of view that since internet cannot replace the newspapers, the same is true with the banks. Being a crypto lover, i would love to see banks eliminated but does these big people with so much money will let that happen 
Most of the time I would not agree with them but I think they are right on this one, bitcoin allows you to be your own bank, this may make it seem as if banks can be replaced if everyone can become their own bank right? No, there are too many people that simply do not have the necessary knowledge and ability to protect their coins, you can give them a detailed guide about how to do this, you could even give them a hardware wallet, they will find a way to lose their coins and people like that have no option but to use banks to protect their moeny.
