My hard drive is just magnetic domains, but I still interact with files. Constructs can be interacted with. I can also bang my head on the car door, even though both are actually just atoms.
Car door and head are just labels on group of atoms, when you banged your head the collision was real. Try banging your head against Amazon or Oracle. Where do you start? The hard drive holding the contracts? The buildings? The web servers? The receptionist?
