No car, no property, no phone number.
I don’t think a bank having my social security number is a privacy risk.
I do not give my name when I buy groceries or 99% of purchases. I don’t see your point.
It’s okay to be naive! The video talks about what data your bank has and how that gets used, as a security professional I know how all of this data is tied together plus the other data (assuming you don’t vote either?), and you don’t think there is anything tied to you so cool. Have fun with that. Keep pushing crypto.
