Most people don’t label 17 year olds as “children”. The process is something more like baby>toddler>child>pre-teen>teen/adolescence>young adulthood>adulthood.
Since everyone matures at different levels at different times, and maturity itself is subjective, most societies air on the side of caution by legally defining people as minors (not children). They are called this because they are still in a state of cognitive development. The ones who are above average are the exception to the rule.
It makes sense why we do this, because minors are supposed to be ushered into adulthood with gradual increases in freedom, such as being able to drive with a permit or go to school dances by themselves before they are considered a tax-paying citizen.


They are all in a world of debauchery that the commoners are only half-aware of, is my suspicion. Sort of like, once you try a single hard drug, you are probably more likely to try more or progressively harder drugs. Once you break the wall of trying one thing you know is terrible, your walls are broken down to making ever-worse decisions.
The nature of dopamine is to want more, newer, novel experiences. If that is driven by sick, psychopathic and unrestrained impulses (the same thing that drove their impulse to conquer business or politics), it will always get progressively worse and more extreme.
