What for? My grocery store (and every other merchant I frequent) already knows and tracks what I buy. Nothing would stop them selling the data to advertisers, even if I paid for my bread in Bitcoin.
Mitigation, not elimination. 'Cuz not every purchase uses a loyalty card that ties it to you, nor does every grocery store have facial recognition, nor do any grocery stores report their transactions to your card provider. Plus the (hopefully) most impactful, paying in plastic usually costs ~3% more.
