You cannot state that without saying how much is spent per passenger or per mile traveled and the marginal cost in lives of a dollar saved there. A similar line of reasoning would be “In this developed country that I live in, no one dies from being poisoned by tap water. I oppose this massive overspend on making tap water potable! The resources used to reach this absolute would certainly save more lives per dollar elsewhere”. How much would we save my making tap water less potable? What would be the consequences if we did? Sometimes, absolute safety or near-absolute-safety is within reach and is the sweet spot for smart engineering.
