Scary stuff how the banks are so in control of our lives and can cut us off from civilisation by closing our bank accounts.
This has been a problem with banks since forever really. You buy into their system, they own you and the use of your money.
This leads me to think a bank blacklist would be an interesting and useful idea, if it doesn't already exist. A bank doesn't play nice with users of bitcoin? Well now they're on the list. Lost business for them, more press for bitcoin "trying" to be "legitimate".
Bitcoin will be used for nefarious purposes as well as good.. Quit kidding yourself.
