As one of those guys, and speaking for detail-oriented people everywhere, we LOVE it when there are bright-line rules like the one for the Air Nomads crossing borders established. "Flash your Air Nomad passport, get waved through" makes ones life very, very simple.

(In real life, every job I've ever had has required damn stringent documentation of everything I do during it. I'm happy to do it; I love being able to smugly point to a big stack of properly filled out requisition forms and say "I did everything right, buddy, now you have to cough up the goods. And sign that I took possession." But sometimes it's nice for me to just be able to flash my ID, sign my name, and get things validated.)
