I personally think the whole idea with Bitcoin was, to bypass institutions like Banks or third party payment systems and to be a alternative for these systems. People must remember that these services were part of the problem and this is why Satoshi developed this payment system, to improve on these payment systems and to ultimately replace them.
We do not need Banks to destroy pseudo-anonymity with all their KYC/AML rubbish. ^hmmmm^
i am not quiet so sure about this but i've heard some of my friends say that there are already banks accepting crypto or bitcoin to be exact, and i've also heard that there are several establishments and corpprations that are in partnership with cryptocurrencies, but honestly even one of them i had never tried.
