If people don't update their views, then I'm already golden and this discussion can do no damage. If people think that these arguments are too paranoid then they are already not paranoid enough and this discussion can do no damage. The fear is that a person who would otherwise be responsible might suspect that boxing is theoretically possible, update their beliefs about the dangers of uFAI (the theoretical possibility of a thing is undoubtedly correlated to the practical possibility), and therefore do less to avoid it. Even if the odds of this are small, it would be an issue. I concluded that the expected benefit I cite is small but large enough to offset this risk.
