Rapunzel became the most beautiful child under the sun. When she was twelve years old, the sorceress locked her in a tower that stood in a forest and that had neither a door nor a stairway, but only a tiny little window at the very top.
1 -- Moral Lessons
All retellings pf Rapunzel focuses on restricting children and keeping them from growing up exposed to the world. Literally, Rapunzel is always locked away in a tower at Gothel's wishes. Ultimately, they all end with Gothel banishing or losing Rapunzel to those she's found from the "outside world." Though it's true that Gothel kidnapped Rapunzel as a baby, it also makes her akin to a surrogate mother. As a surrogate mother, she lost Rapunzel when Rapunzel finds that theres more to life and love than her tower and her fake mother.
