Aren't cabbage kids stories just lies hinting that children arrive through hidden means, wrapped in stories rather than lineage and no need to question it too deeply?

Aren't changelings and cabbage kids just stories to hide the fabrication process of entities?

A changeling was supposed to be a changed child: a child stolen by spirits and replaced with something that only looked human which cried incessantly, left in its cradle wrapped in moss or leaves.

Or the convenient stories of boys who came from cabbage patches and girls from rose bushes, a fantasy which turned secrecy into magic.

World’s fairs and amusement parks were the remains of the previous burnt down brick world.

There, in the late 1890s, supposedly "premature infants" were placed on display in glass incubators for visitors to observe, supposedly "abandoned babies" from the evill mankind ...

These were babies with no names ...
Presented not as kin, but as curiosities ...

The baby in the machine had no past and no one seemed troubled by that.
