Only if you don't plan to have any treasure fall in those traps.
IMO, The reason NPCs shouldnt put their value into traps is because it sucks for the dungeon delvers to realize that half of the treasure that should be in their laps is instead stuck to walls and floors.. invested in an infrastructure they can't realistically cash in on.
On the other hand, when players invest in these traps, they get their money's worth over time by successfully protecting what they hoped to, or even better, a little extra scratch that lets em run even.
