Let’s be real here, the only thing these banks would do is impose more draconian KYC/AML on customers to cover their ass. Whatever it takes to tick that box.
And it's overt surveillance, where privacy is blatantly criminalized, rather than the type of covert mass-surveillance we're accustomed to hearing about, where a 3 letter agency secretly deprives you of your privacy, showing you enough respect to not demand that you knowingly give it up.
So-called anti-money laundering laws are a complete and utter violation of democratic principles, namely privacy and due process, and create the kind of surveillance apparatus that puts the populace under the complete control of the state.
The public support for this kind of double standard translates to: "we support you being secure in your rights, unless you want to do something meaningful, like send, receive or possess economic value".
As long as these broad invasions of AML laws into privacy are in place, the West's support for the principles of liberal democracy looks superficial.
