When DoorDash or whatever courier comes to a restaurant, they pick up “order number”. That order number is in essence just private IP. Courier translates it to address=public ip.
It follows that the restaurant writes the address on every delivery. Do they ID each recipient?
In the original example the Parisian bars sells and sends the alcohol.
You’ve modified that to introduce a proxy, DoorDash, that now sells and sends the alcohol. If DoorDash sells it they’re the ones in trouble in your example.
