Another thing to consider is your credit card rewards cash back etc are really trading your privacy for a little rounding error worth of discount in comparison to using cash.
You may also save far more money going cash only. E.g. some local restaurants near me give you like 5% off paying in cash. Gas is generally cheaper cash price vs card price or debit fee. You have a big job with a contractor, tell them you might be interested in paying cash and they might offer you a substantial discount.
Contractors, but also cosmetic health work. Invisalign, veneers, plastic surgery, etc. Probably most big-ticket items or services that you're not buying from a megacorp.
Sometimes they'll give even more than 5% because they can keep it off their books completely, but in those cases, they want physical cash--not just a check to avoid credit card fees.

How much privacy really? If I get mostly $20s from the ATM, and the merchant does daily deposits of most of the $20s they get, why wouldn't banks start scanning and tracking serial numbers (if they don't already), if my purchasing habits are actually valuable?
