The world is still at an early stage of crypto adoption. This type of preventative measures reflect real fears of banks worldwide - both of the existential threat that bitcoin represents, but also of the short term fears of the volatility of the crypto investments (they don't want people defaulting on their credit). The good news is that such early measures are part of a natural progression: it is clear that cryptocurrencies are here to stay (and that they will have a dramatic influence on our economic world). As such, as the fears subside and people start viewing the currencies responsibly, more sane policies will arise.
