Agree. But not every parent is capable, and the kid has to suffer because of that.
I just have to look at how much sweets and sugar the kids in the Kindergarten of my daughter eat.  They are 3 to 6 years old and eat mostly cookies and chocolate.
People are stupid unfortunately.
I’m in favour of certain protections.
Not all laws are bad ;) 

 I disagree, but, that's really my idealism peaking through. 

These are the kinds of issues that sort themselves out in a few generations. And, well, we're seeing that now.
