Good PCs will abuse the trap rules just to mess with the Tax collectors, causing an entire war
between them and the country once the country realizes they have 50,000gp
(Think of that in NPC terms...)
Fighter:"Hey guys, another tax collector is walking up to the door again."
Cleric:"Don't worry we'll---"
Kobold Artificer "Wait for it..."
NPC "My eeeyes! What? I can't hear anything either? Help! Help!"
Blindness/Deafness trap ftw*
