What's the purpose of AN 2.61?
I suppose "to die without getting enough" is a colloquial expression for being insatiable, indefatigable.

This is an emphatic way of saying that women have a strong instinctual desire to bear children. If you polled a big enough sample of women I suspect majority would say they like to have children, enjoy having children, and many would say they'd want to have more then one child if allowed by the living circumstances.

The point of this in context of Buddha's teaching is that samsara has built-in mechanisms for self-continuation. Natural phenomena have innate tendency to proliferate, to continue, to support their kin, to procreate. 

Left unchecked, the stream of samsara rolls forward endlessly regenerating ignorance, confusion, desire, suffering, and desire to escape suffering. It is the ignorant pursuit of this desire is what supports the stream's momentum to roll on and on.
