After 6 cross-country moves in 7 years, this is also my strategy for travel and moving. I have an anxiety disorder and traveling is just the worst thing ever for me. I used to be an over-packer, because I was always worried I'd need something and I wouldn't have it. Now I pack twice -- once with everything I think I'll need, then I go back later with fresh eyes and get rid of anything I could do without. I actually prefer bags with no internal organization system because I use ziploc bags to keep certain things together (cables, bathroom stuff). I like your explanation about minimizing your own chaos to deal with the chaos of traveling, it's a classic anxiety coping mechanism with the bonus of actually working.
