The genius is that the US isn't even really enforcing it! I did it wrong (used a really large ziplock bag instead of a small one) and I got an "A for effort" and then got waved on because I'm cute. I even *offered* to throw some stuff out.
We get these crazy ideas and don't really mean them, and then the rest of the world follows but doesn't realize we were just brainstorming, not really enacting policy.
"I set out alone, finding no companion to cheer the way with friendly intercourse, and no party of travellers with whom to associate myself. Swayed by an overmastering impulse within me, and a long-cherished desire to visit those glorious sanctuaries, I resolved to quit all my friends and tear myself away from my home."
---Ibn Battuta, CE 1325
