It depends on what context she was saying this in. She might have been being sarcastic and saying that "no woman should be authorized to stay at home and raise her children" in the reverse of what was commonly said or told to women during her time, that (bourgeois and upper class) women should not have the choice to participate in a work or public life. Or she could have meant it in exactly that context, who knows. Here are some other Simone de Beauvoir quotes...
"Man is defined as a human being and a woman as a female - whenever she behaves as a human being she is said to imitate the male."
"No one is more arrogant toward women, more aggressive or scornful, than the man who is anxious about his virility."
"Society cares for the individual only so far as he is profitable."
"The most mediocre of males feels himself a demigod as compared with women."
"Society, being codified by man, decrees that woman is inferior; she can do away with this inferiority only by destroying the male's superiority."
"This has always been a man's world, and none of the reasons that have been offered in explanation have seemed adequate."
"Why one man rather than another? It was odd. You find yourself involved with a fellow for life just because he was the one that you met when you were nineteen."
"To catch a husband is an art; to hold him is a job."
"When an individual is kept in a situation of inferiority, the fact is that he does become inferior."
You have to understand that Simone de Beauvoir lived in a different time. She was born in 1908 and she published "The Second Sex" in the 1940s. Second-wave feminism occurred in the 60s and 70s. I haven't read anything by Simone de Beauvoir (yet), but I find her to be thoughtful and as I identify to some degree with Existentialism, I find her interesting.
