There is no absolute mental difference between children and adults. Even race, class, and gender have more scientific validity as social groupings.
The construct of childhood is a violation of human rights. Forcing children to live with people who don't care about them, forcing them to go to schools where they don't learn anything and are punished for defending themselves, and denying them the freedom to associate with whomever they please, sexually or not, is a violation of liberty.
The construct of childhood continues because the lowest adults need a group of people to look down on and pretend to care about. The majority of adults (women and men) want to be raped by the elites (billionaires, true white men, and hot white women) themselves, and watching children get raped by important people provides a voyeuristic masochism for the lowest adults.
If something is not done to liberate children from the yokes of oppression put on them by beta men and ugly women, all of humanity is doomed to degrade and die off as we know it.
Although that wouldn't be a shame.
