Generally, when most people buy a product which comes in a package, it is not "a very dumb idea" to assume that they will open the package.
I don't know about you, but most people don't have extra money to drop on a game box that they will never open.
You got my point wrong. This is only about the digital codes included in the box. There is just no point to include digital codes to a box version if you have to open the box to get them.
Usually digital codes are added to physical versions for collectors. That way they can preserve the box and just use the digital codes to play. Another reason to add digital codes to a box version is to enable your customers to play the game right from the start without having to wait until the box is shipped to them. If the digital codes are in the box neither of these reasons is valid....
Of course most people just want to play the game and open the box nevertheless. And in most cases these people install the game from the DVD and the digital download codes are just useless.....
