Because these were Central Bank policies against money laundering and other illegal activities in which even corruption may be monitor as well. The only thing that i hate in the bank is that very strict requirements when opening an account but i considered this a natural to ensure that money was not came from illegal activities like drugs and smuggling that is why some syndicates related to drugs and smuggling are not depositing their money in the banks but instead they will bury it and some are using the bitcoin to hide their illegal wealth.
