There will always be weird tail risks. The law should only get involved where there are widespread systemic problems.
People are occasionally hospitalized due to self, family, or friends handling food improperly. That doesn't warrant a legal intervention whereas dining establishments do.

Nope, that's exactly what I say. The law cannot reasonably replace responsible parenting if society is to remain a pleasant place to live.
I live in extremely fire prone areas.
Many of us are pretty damn okay at beating back the flame and controlling the flow of the worst of things away from homes, but nobody is perfect.
We don't expect every family and parent in these areas to have fire fighting skills, self evacuation is recommended.
Parents every where now find themselves surrounded by the delibrately laid gasoline of addictive social media and grooming risks et al. and it's infeasible to expect every parent be skilled in defensive cyber secuirty.
It's reasonable to expect communities to want simple barriers and means of protection, the existance of reasonable control and throttling options for parents.
