There are some people in this world, who simply find maggots revolting,
or they believe that only pure humans are the supreme and perfect beings.
Anyway, they absolutely refuse to use protein protozoa, or any medical-grade silicone synthetic prosthetic organs.
They want human ones.
And there are also people in this world, who are simply too poor to make ends meet.
So, they willingly sell off one of their eyes, or both, or their hands, feet, liver, kidneys.
In short, whatever is valuable, they sell.
With such a pure supply-and-demand relationship, the rest is left to the market.
That's capitalism for you.
"Scavengers provide organ transplants for the rich, with substantial volume guaranteed; it's a major source of income for the Whirlpool Gang, and because of the pressure from the demand side, even the Security Bureau can't completely cut off this source. If you have enemies, sell them to the Scavengers, and nobody will dare to follow up on the investigation."
