I agree. Especially for a game in which we want the characters to stick around and be part of ongoing narratives while still participating in battles on a regular basis.I agree that they aren't "necessary" but I'm in the midst of running a long campaign for the first time in a system without hit points, and wow do hit points make life as a GM much easier. That ablative plot armor is almost better for GMs than it is for PCs because it allows you to prepare and run challenges in a much more predictable fashion. Without hit points, the line between an easy walk over and a TPK is just super narrow. Without hit points, too many things come down to single die rolls. Hit points mitigate against luck and let the dice fall where they may so much better than other concepts.
You could also make a more abstract or less granular rule for injury and wounds, maybe something like the wound levels Ars Magica or the White Wolf Storyteller games used. But HP definitely serve the narrativist goal of having ongoing heroes who aren't quickly crippled or killed by regular participation in combat.
