She states that desire is necessary and unavoidable but admits that it leads to suffering. Not getting what you want, when you really do want it
is suffering and she has no answer for that. If desire is so good, why is there still so much suffering in the world? How is that working out?
A wholesome desire for a wholesome outcome is okay and the Buddhist teachings do not prohibit wholesome desires (chandha vs. tanha).

It is the desire to end all desires and that is wholesome with a peaceful outcome.
To use an anology, let's say that the relativists are right and there are no absolute truths of any kind. Someone might retort: "but that is an absolute truth, you contradicted yourself!" The relativists could respond by saying that "the only absolute truth is that there are no [other] absolute truths" and that statement is perfectly fine.
