I think becoming an emancipated minor varies a lot by jurisdiction. You may need to look hard at what type of income works for you. I.e. letting a guardian take some income in an inappropriate fashion may actually help you formally emancipate through the courts. Identifying antiques/collectibles is a skill that can pay off well. Ghost writing for bad students (and now bad employees) can pay well and has a payer that wants to keep things discreet but that is income you probably wouldn't want to use to later argue you are financially independent.
