If you want to make the example more intuitive you can imagine strain of fungi that has the potential to evolve to an incredibly potent medicine (prolonging life by 30 years) some day in the future. The fungi grows on everyones socks except your just by random chance.
Suddenly everyone in the world owns a vial of potentially the elixir of life, except you. Can you still buy tomatoes when your neighborhood has sold their socks to Bezos and they suddenly each have a million bucks of cash in hand?
