The point is that she spent $50k because she spent too much time not focusing on starting a family and instead was doing something else which was probably a self-centered lifestyle. She would have nothing to say to the man who bought the car.

A man can father children and buy a extravagant car in his 20s or his 50s. A woman freezing her eggs is doing so in response to a biological constraint that men don't face; they aren't comparable situations.

A luxury sports car could be a signal used to attract mates, like colorful plumage on a bird. So he might also be spending that 50k on having children (albeit indirectly).

Men buy them for themselves, not to "haul in the babes."

In the same way that women put on makeup for themselves. However, the desire to be attractive "for ourselves" is baked into our genes precisely because it helped our ancestors attract members of the opposite sex too.

For all the midlife crises, it doesn't really help someone who's not already confident/sexy/rich, though. It's an expensive accessory, like a watch. Makeup is a fair analogy, in that men like to impress other men with their cars and (most) women don't bother being made-up everyday for men.

We can't assume someone raised by that sort of parent will be a positive addition to society.

By what sort of parent?

She doesn’t have or raise children. She freezes some eggs, which, with some luck, could later provide her with the possibility to have and raise children.
