the lack of privacy at a business isn't a problem baked into cash. cash helps solve that problem because I don't need to go to a place of business to use it. It can be exchanged anywhere in reasonable amounts, and I don't have to deposit it I can just keep it and use it.

my wife and I always keep some cash on hand in case of some sort of problem with the card, or tap device etc. never had my cash declined because a computer thought some other purchases that afternoon looked suspicious.

It’s way more private than all of your transaction history rolled up by your card issuer.

Does some central authority have access to and the compute power to correlate all of the data available in those video feeds? No

You only need to know where the person was or when crime was committed,

You’re right but I don’t think we’re solving for the same thing.
