Actually the laws as written DON'T impose any such requirement. Banks generally choose to implement policies that do that, but it is not required. And during COVID, many banks changed those policies.
https://www.bitsaboutmoney.com/archive/kyc-and-aml-beyond-th... goes into this. The primary concern for regulators is that you must have made statements to the bank that you can later be put in jail for lying about. And the bank must have approved procedures in place for identifying when transactions are high enough risk to decide to take verification steps.
On your comments about judges, you apparently have substantially more confidence in the common sense applied by the legal system than I do. Don't forget we now have a Supreme Court judge (Amy Barrett) who is on record, in a legal paper no less, saying that fiat money and the Fed are obviously unconstitutional, and judges should handle that by simply avoiding ever considering the question. (Read https://scholarship.law.nd.edu/law_faculty_scholarship/1304/ if you think I'm making that up.)
Does this sound like an excess of common sense?
