Some people choose not to carry them, that's all. Some people love matches (raises hand), others hate them and only use lighters and spark-based ignition systems. I swear by nalgene bottles, others at them. There is no one right answer to gear selection. You take what you know how to use, like, and can afford. Every kit is a balancing act.
