What about the people who make a living by playing video games? Or the people who struggled with education and decided that adult entertainment is something they like? If no one in a family depends on someone, it can also mean that the other members of the family are equally independent, it's not unheard of. As for needing money to farm, not really, provided you know what sort of plants to look for and how to harvest the seeds properly, all you need is an empty piece of land (which is highly abundant in forested/wooded areas naturally) and some water. You'll argue against all of this obviously because you can't handle the fact that people can be independent.
