User blog comment:PyroNacht/COPPA: Difference Between Maturity and Safety/@comment-5956954-20170512001750

So, the main points simplified:
 * Kids can be mature, but they are not always a prodigy in book knowledge.
 * Parents need to learn what Parental Controls are. COPPA is useless without the recognition of parental controls and a proxy like BlueCoat.

In either case, it should be fairly obvious that maturity is still the result of feeling like the king of the world (snowflake syndrome), and the brain is still that of a child: stupid and impressionable. Thank you, COPPA.
