It's better that kids be harmed than the government starts intervening with regulation.
Either kids aren't actually being harmed, government regulation will cause more harm, or parents should parent their kids. Either way, nothing about the solution should involve me.
> or parents should parent their kids
Parents are voters. One of the way they parent is by being civically active in their kids’ interest.
If you will never interact with or rely on people who are currently children, then that's plausible. Unfortunately, it is not possible to live that way, so your suggestion is not really under consideration.
