Light infantry are valuable in city defense. With bonuses they're useful, and you can hide them under other units to look more frightening. It's common for me to stick a couple under a single Heavy Infantry and make weaker cities look well-defended. Plundering them doesn't get you much of anything, but with bonuses they become useful. I'll pile them in with a dragon+hero as fodder troops on less difficult battles.
Overall they're the weakest land unit. But that's their role. Cheap, decently mobile, and only really useful if you can boost their strength. There's really nothing wrong with some units not having a vital niche that they fill better than any other unit.
