We are working on this better model in the Ethereum ecosystem via technologies like Zero Knowledge Proofs and private attestations. The Ethereum Attestation Service has been using the example of proving to the bartender that you are over 21 without disclosing your birth date. https://docs.attest.org/docs/core--concepts/privacy
This is all new and rapidly evolving technology but giving apps / agents / others just the information they need to know while having a credibly neutral, private, and trustless database mediating is a true cypherpunk vision of how the internet should work and it's being built by people with the right ethos and principles to be as reliable, well engineered, and long lasting as the internet itself.
Where did the OP even ask for a "trustless database" or "cyberpunk" or anything like that?
It is perfectly reasonable for the delivery service to be trusted. After all, they're going to take the physical package, so the business must trust them, and need to know where to deliver it, so the individual must trust them. An individual can request a token for the business and the delivery service can validate it, without the address ever being given to the business.
None of this requires a blockchain to make it slower and inexplicably public.
