Why do so many women have a hard time answering this question?

Girl's I've been dating I've asked the question of "Besides a warm mouth and a vagina, what would you bring to the table?" I also add in the fact that I can cook, clean, pay bills, and handle the other domestic responsibilities myself. So far, only one woman has given anything remotely worth listening to. The others either can't answer the question, never thought about the question, or just stop talking to my all together. I took this to an international group as well, and even they were stumped.
