The comment I was responding to asked for examples of “lotteries you don't see, because you're used to them, and they're just part of how the world works, like this one is to the people in the story”. The comment wasn't asking for “deliberate deaths caused by adherence to some tradition”.

Expanding the idea of "lottery" that much makes it meaningless, and useless as social commentary. Sometimes people die of cancer, or lightning, or shark attacks, and eventually of old age. What insight is there in calling them "lotteries you don't see"?

None of your three examples are actions that are willingly (either actively or passively) carried out collectively by people in society.
