We all make our own decisions as to what our priorities to carry are. I tend to agree with those who feel fire starting tools/materials are so light and inexpensive, I won't go anywhere without them.
Perhaps one other point to consider is just as knife can help you make other tools such as a long spear, bow, help provide shelter, etc. , I feel that fire can also become another tools itself and that help boost its priority for me.
Plus it gives me great comfort when I out for a night to have a fire going, and we always hear that attitude is a big factor in survival. So, that said, go with what makes you most comfortable.
