There is a French psychologist called Françoise Dolto who agrees with you, she even write a book about it. She says a great deal of the problems with adolescents today (where today is in the past century, this is not a recent book) is that they are not needed. So, exactly like adults who are not needed and left to their own devices, they develop para-social hierarchies, and/or turn to crime and develop mood problems. Your teen can probably balance a checkbook and pay bills. Teens also eventually come to a point where they're really interested in driving and, in America, you can use that to make them run errands, take younger siblings to school, and so on. Even a scooter works fine for a lot of that. Also, to use an example from my real life, as a teen I just... stayed with the other women and talked about their lives and offered emotional support, helped smooth over relationships, that sort of thing. Yeah I wouldn't have been able to negotiate someone's salary or something but most teens can tell Aunt Marie that Aunt Alice wants her coffee machine back while eliding the "and thinks you're ungrateful and live in a hovel" part. And I helped them with math too.
