I agree with you, but it’s generally not too far off. The prefrontal cortex is the most recent part of the brain to evolve, and it’s the most “human” part of the brain. The PFC continues to develop over adolescence, only finishing in the early-mid 20s.
That’s the part of your brain responsible for pushing back on emotion driven reactions and doing more strategic planning, among other things.
Well put like that, it sounds a bit dumb to put an arbitrary number like 21 to some profound sense of “it’s time to adult, now”
