She's scared. Think about it for a second. She knows what will happen if she tries to. If we were to follow your words, then all abuse victims should do the sh** you did. That's not wrong in any way, in fact that is reccommended. However, what then? She ran away, hid herself and took the amount of money then what? Where will she go? How will she gain a living? He**, she had to go with another person. Her little brother. In her eyes, her little brother is a little kid who shouldn't be going through the cruel outside world, she doesn't want him to starve, she doesn't want him to be sold, she doesn't want him to see what she's become, she doesn't want him to be a slave. If you're trying to be smart, then try being in her place from the start.
