That misses the point by a mile and a half: nobody let's their children eat unlimited amounts of chocolate. They do, however, let their children access Tiltok, Youtube, etc.
I wanted to eat unlimited junk food when I was a kid but my parents wouldn't let me.
You can change it even to unlimited protein shakes. It is the same point. It is almost like kids are kind of stupid if you let them do whatever they want.
