It makes perfect sense. Man made the wall. Man made the car. Man makes mistakes.
The LORD made man. The LORD does not make mistakes. On top of this, we were made in His image, not a tattoo or piercing in sight. To change the image is to declare His image not perfect. Perfection cannot be improved upon. Yet imperfection is never enough, and never enough is endless suffering. A perfect wall would be ruined by an unnecessary picture. A perfect car tainted by an imperfect bumper sticker.
When the LORD looked at His creation He declared it very good. When He sees it suffering then He is saddened. A tattoo whether you or the people you know want to accept it or not is a manifestation of suffering, it only comes from an initial thought of inadequacy.
