The problem here is that your job is then defined at your birth based on the genitalia with which you're born. That's more or less arbitrary. What if a female is better able to contribute to society as, say, a doctor? What if a male wants to stay home and run a family? People should have the freedom to choose how they live their lives; they should be able to contribute to society in any way they please.
