I don't think the example was perfect which explains your wife's reaction.

Think of it more like the first delivery guy/girl left his/her car outside and wrote 123 on it. Then walked back.

The next one sees the car with a sign saying 123 and won't even ring the door bell or leave a package. Now you haven't gotten the package twice, it has not been delivered twice.

Sure you can complain that there's a car outside your home but in digital system you won't even see it. It would also cost the deliver firm a car for every package but that is not your problem and again, in the digital world the cost is a lot less than a car.

There is an argument that the street would be filled up with delivery vans ans there would be no more room for new deliveries to you or your neighbors but that is a limitation you could talk about. You probably can't handle an infinite number of packages delivered at the same time either and you won't wait an infinite amount of time for any specific package.

Try this version with your wife.
