To be clear then, your objection is that any physical device that seems to add is doing something different from a “theoretical” device that doesn’t actually get built.
(The device made of lego is a red herring, since your argument also applies to real computers.)
I suppose I would say that if the physical device is working properly, it is indeed doing addition. But as a physical device, it always has the potential to fail.
