Despite your oversight I still agree. An upgraded finewood bow will still carry you just fine until you are ready to get the bow that comes after huntsman.

Bows are easily uncontested as the S class weapon type due to their range and the versatility provided by having multiple ammo options, but during that whole swamp phase pierce damage is underwhelming no matter which way you try to look at it. And once you get to the mountains, the wolves and drakes are pretty light in the HP department anyway, whereas most other things there are probably best taken on with some calm and controlled melee combat. Golems will take all day to kill while fenrings might not leave you with a lot of spare stamina for shooting due to their ability to chase.

You might need to hit some enemies once or twice extra with the finewood bow but taking that extra time to stock yourself with some cheap ammo isn't going to take you as far out of your way as a whole additional iron-sink. Not only that but if you need bow skill, you get the same XP regardless of your damage or target, so keeping with a weaker bow can even help to set you up with even better DPS later.

The huntsman bow and finewood bow also share the same max range if the wiki is to be believed.
Besides damage the other benefits that the huntsman bow has over finewood are small and spread out to the point that you would probably never notice them. It has double the knockback (but 10 knockback is still pathetic). And it produces half of the noise radius for both your firing and your arrow impact. The former won't make a difference unless you are performing a bow sneak attack from a close range for some reason, while the latter only matters if you keep missing your sneak shots by an embarrassing margin.

The only other thing is that huntsman is only slightly more accurate than finewood but that shouldn't really be an excuse for missing unless you are already attacking from a range where the enemies are too dumb to respond properly.
