Many has the thought that bank is not really looking closer to the bitcoin structure and sooner will join the system, but I think, they already know how good the structure is and their ego don't allow them to give it away, so they are developing a better system, with the basics of bitcoin and reducing the cons in this system, and may put a new term for the whole thing. 
I like the bitcoin idea and even lot of business support the same. There is nothing illegal and many has yet to understand that. Even many merchant account providers are now providing services to bitcoin products & services. The number is also increasing and soon the whole world will accept the bitcoin system.
