Another few questions to ask:
Who is going to keep on paying for her being frozen? Her parents may do that for the rest of their lives, but then who will pay after they are gone?
What if the cryonics business that is keeping her frozen goes out of business?
Who is going to expend resources to revive the person, cure the disease and get her trained for living in the world of then. (It won't be cheap!)
If there are relatives (distant at that) living at that time, then will they take care of this stranger?
