Because she was against it?
Those things are based in principles. In principle I have the right to state funds for all of my children. Because I am against such subsidies I have decided not to request them, even though the state continues to insist that I should and that it is my right. And even though I pay for other people exercising this right.
For Ayn Rand to rail a life long in many different pamphlets against state run entities only to turn around and to use them when times were a bit tougher seems hypocritical to me.
