The firesteel is not only a backup. Itīs a bit of redundancy as it has different points of failure.
The two major modes of failure for butane lighters that I experienced were leakage (maybe due to inadvertantly opening the valve during storage) and clogging (mainly in rarely used lighters). The firesteel will not suffer either of those. I never had butane lighter that actually stopped working because of used up fuel.
I still carry one or two butane lighters anyway.
