Living in the now in this way hurts no one. It is useful because it helps them as children (for such a short time!!) to do what they want to do, which is to play and interact over a game... to have fun. Childhood is for having fun. For playing. For learning to navigate personal autonomy and sovereignty. For practicing at real life.
Kids who are raised in whole life evolution without school do not need to rebel to exert power. They are given the power of self direction and trusted to be who they need to be while their parents facilitate their passions and ensure their safety. They return the empathy they receive to others throughout their lives, mirroring the compassion and acceptance modeled to them.
