Men have an extended time period to be fathers and it is virtually their whole lives. Who could blame a woman for wanting to have children later in their lives too. If they have the money and can find a donor to carry the baby, then it is their decision.
There is nothing wrong with a woman choosing to freeze her eggs. Women are choosing to work on their careers, getting married later in life, or not getting married at all. Waiting to start a family is risky when it comes to a woman's fertility. The odds of being able to bear a child go down dramatically with age. Freezing eggs as a precaution is a smart precautionary move.
