Assuming the reason for these laws is to protect children from pornography, you could ask, what are the specific harms from pornography? You could identify those harms through scientific study (some have been done; it appears the harms are mostly due to a lack of education and understanding about what's going on in porn) and address them (educate children to understand what's going on intellectually/emotionally and how to treat people with respect). But that would require talking to kids about sex, which adults are petrified of. Our culture is puritanical, and uses fear and shame to avoid dealing with things like sex. It then perpetuates this fear and shame onto each generation, and it pervades every product and service we have. So we could try fighting the irrational fear and become less afraid of sex (and pornography would probably change because of it). But good luck doing that in this country.
A while back, in my country parents protested against their daughters getting free HPV shots.
Couldn't handle the idea that their kids are separately embodied beings, you see.
Plus I'd wager the long word "papillomavirus" scared most of those folks.
So now we have higher STD rates and a significant number of young women permanently traumatized by being denied healthcare just because their parents were too obsessed with their private parts.
