One thing to consider is that you won't be building fresh fires from scratch all that frequently. Even with mediocre wood, you can usually coax last night's fire to life without using matches or lighter to cook breakfast. On one occasion, using a really good desert hardwood (ironwood), we were able to cook breakfast on the still hotly coals from the evening fire without doing a thing. So if you are staying in one spot, you could go days without using your matches.

People BM (before matches) went to some lengths to preserve their fires, even carrying live coals from camp to camp. When sulphur matches were introduced they were wildly popular and replaced flint and steel rather quickly.
