>An example of this is that freezing your eggs costs upwards of $30k, and is still viewed as something only very select late 30's successful women do.

Isn't that also very unreliable ? When we went to IVF clinic they told us that freezing the eggs has much lower chance of them being usable compared to fertilized eggs.

Even if you make egg freezing cheap, it will still have an abysmal success rate (particularly if a woman waits until her 30s to have the eggs freezed), and should rationally be viewed as a hail Mary of last resort. This should not be viewed as the default rational path towards pregnancy, even if it were free. A society which is structured to encourage this path is setting people up for serious disappointment.
