Sure, but look; if this were a discussion about people making irresponsible decisions that result in themselves getting killed, I can sympathize with the philosophy that we can simply encourage people to voluntarily avoid those things by making other choices preferable. But when people make irresponsible decisions that result in third parties being killed, this is when we make laws and ban things. This is why, for example, there is a ban on intoxicated driving. Not because of the risk of harm to the drunk driver, but because of the risk to everybody else, who want to stop volunteering to share roads with drunk drivers.
