Except that you would all be murderers and the courts could possibly strip you of whatever title or property you were trying to take?
There will probably be professional focuses within a small family but there is nothing stopping you from branching out, leaving the house, and going about your own life. If dad happens to be a carpenter and you want to own the business, it'd make more sense to learn from him passively (this will help raise your skill level), get involved in the family business, and have him will everything to you upon his (hopefully natural) death.
