71. The crime is endangerment of the welfare of a minor.

You're focusing on the word "endangerment" and taking it to mean only endangerment of one's physical safety. One's well-being can be endangered in other ways. If another parent showed my young child a pornographic movie or a graphically violent movie, I would consider that parent to have endangered the psychological well-being of my child. Considering that pedophiles sometimes start out showing their victims pornography, I absolutely believe this should be considered a criminal offense. Maybe you think teenagers are too old to be afforded that protection under the law. If that is the case, you should make that argument instead of focusing on a narrow and irrelevant interpretation of "endangerment."

ETA - The strippers in this case did more than provide a "visual," but I'm addressing your hypothetical of what if were only a sexually explicit visual (and I don't think all nudity is sexually explicit, but this was).
