Parents hold the most legitimate broad authority precisely because children lack the maturity to avoid self-destructive choices. Government’s role is narrower — protecting the rights of rational adults. The confusion between the two is because people who want government to parent them are already behaving like children
I like this approach, I try to raise my kids to be rational. So it’s okay for them to ask some questions of me when they don’t like the decision, my word is still final, I’m the parent and they are the child, but better that they question things sometimes rather than never question or question all the time as OP is insinuating.
