Yes, I know, it doesn't always make sense. I justify it by using experts in trapmaking in the tribes that use them. If you make a kobold expert 3, this provides a +6 bonus (class skill, 6 ranks at third level) and a +2 racial bonus.

Crafting even the very simple Swinging Block Trap (DMG p71) would cost 234 gp and take about 10 weeks to complete.

Do you how hard it is to make a trap vs. weapons. You got complex arrow-firing, blade-swinging, death-dealing action in a trap. A weapon is a glorfied hunk of metal or wood (or other substance). That is why almost all lethal(?) traps are magic or poisonous in nature. Not that a good hole in the ground doesn't work in a pinch.
But, yes as the rules say, it is very hard, and you need to be trained well to make something that will work well and correctly.
