Both, it's a question of economics of scale & time output. Correct?
There were loads of conspiracy theories back in the day why our demented Communist leader Ceaușescu was so obsessed with having so many children, despite difficulties on the country's limited output (energy, foodstuffs etc).
One conspiracy was that he wanted to raise orphaned children as his family's personal loyal army/secret police when they grew up and indoctrinated sufficiently. A planned organic inner party muscle; something that not even Orwell, Hitler, Mussolini, Stalin, Mao, Kim, Saddam, Kony etc. could've imagine in their worst fever dreams.
Another conspiracy was that he wanted, eventually, to turn them into human harvests: organs, blood, hair, marrow bone, anything exploitive out of a human body essentially.
This is where my fringe dystopian hypothesis was inspired.
When China did their one-child policy, I remember vividly some very old people commenting: "Why would they do that? They could just lie to the family, declare it dead, steal it, raise it in some isolated human farm/orphanage for x, y, z purposes."
I didn't knew what those "x, y, z purposes" meant until much later... and wondering who were those old SOBs that talked & thought like that, creeped me the fuck out...
Why have artificial wombs when you could have natural wombs?
It's just a question of gaslighting and re-inventing the universal human rights, separating legal humans and alegal humanoids.
The reason we see it as dystopian is because we've chosen to see it that way. Otherwise... feudal law is retarded, once you look at it this way.
I genuinely don't believe it because, mechanically, it's too input-output exhaustive. It's too sci-fi for me to accept it as reality.
