The 10% stacks additively, each time you do the deal, this status is applied to a different 10%. If you sacrifice 10 fingers, the entire world is guaranteed basic human needs (food, water, shelter, clothing, healthcate, etc…)
Nobody knows you saved them. Would you do it?
If everyone knows about the fact that you can do this deal, would that change your mind?
I’ll be honest: none. I’m not making shady deals like that. Besides, shortcuts always come with giant caveats that you don’t know in advance. Like: how long is this guaranteed for? Will it magically prevent people from depriving others of their needs (murder, arson, imprisonment, torture, etc.)? How will it be sustained, and how would it affect the rest of life on Earth?
No no no, count me out. I’m not taking that deal just to find out it only applies for 1 month or some crap like that and people can still kill each other.
Plus, I like my fingers. I use them every day!
I left the question ambiguous for a reason. I’m glad someone pointed that out. 😉
1 month of universal basic needs met for every human alive could easily be world-reshaping
This is what I think when characters in fiction want achieve inmortality. Yeah dude, inmortality is one thing, but good health is other thing. You can get disabled, unable to walk, even worse, been in a vegetal state, but hey, you are inmortal.
