I agree, but in a paranoid alternative world, the bank employees could share your bank account balance information with criminal organizations that would investigate you and your family, and one day kidnap you and take you or any of your family members, and ask for an amount of money they know you possess.. It's still a trust issue.
Right, hadn't thought about that, they could also leak information.
Luckily in the case of files you can easily do something about it, by encrypting them client-side or using a storage provider client that handles that for you.
