Again, being a leader is not about being a good person or a bad person. Only a good leader or a bad leader. Trying to apply an individual's morality is useless.

Because you're genre-savvy. These people are not. They don't have access to veritable libraries of reading as we do at the touch of their fingers to make comparisons to similar situations either fictional or historical.
To them, the idea that you're willing to put up what should be your most precious thing as a person as collateral shows you are VERY sincere about whatever it is you're saying. Modern wisdom says you don't bet something you can't afford to lose, but for them seeing that you are betting something you can't afford to lose, that means you're 100% not bullshitting, because otherwise... well, you lose it.
