I’m not religous (because of or in spite of Catholic College?), but I’m often surprised how views which I try to reach logically conform to the Bible. Tattoos don’t make any sense. They’re a permanent identification to someone or something other than ones self. What I think of with tattoos is Nazi Germany, prison inmates, or the mark of the devil. On a more practical note, the image of an aging motorcycle rider with the disfigure butterfly tat on exposed on their rear end says it all.
I think you've stumbled upon Natural law.
