Problem is that that situation would only come into play if food became scare, which, under the current mechanics, it never will. And even if a war caused food prices to rise by a factor 10 it would still only cost me 4 million a day, which is still just a drop in the ocean.
Also in that situation people without the project would be effected almost as much as people with it, so the project wouldn't really make a difference.
I get the intent, but it isn't gonna work. And before you ask me to suggest how to make it work... 🤷♂️
