From an ethical point of view what those who think JPJ has done something very wrong, what you believe is:
The right of a child to have a parent until they are 40, 50, 60, 70 years old, overrides the right of an older woman to be a loving parent for 20 - 35 years.
I don't see how anyone can make that call.
The women who choose to do this are not going to burden society (they have the means to fund their own care in old age) and will have a network where there child will have 'family' to love them even when they die.
How does any women here think they have the right to call another woman 'selfish' because she can 'only' parent for 20-30 years?
What you are saying, is the child has a 'right' to their parent being around until they reach XXX years old.
