Now, that makes good sense. You'd need some kind of recognizable clothing, and some kind of structure. And, it sure could work. Sadly, I have been wondering if FEMA is designed to prevent aid from reaching disasters.
I've been part of a relief effort. They handed out yellow vests that said "Mormon Helping Hands".

Some years ago I came up with an idea for NDC, National Disaster Corps. Young people who didn't care for the military could join The NDC and get the same sort of benefits for serving the country armed not with a gun but a shovel and a hard hat. Like The Peace Corps but with heavy equipment. The corps could be organized like the military and even work with the military for transportation and basing. Heck, there are empty bases all over the place they could work out of. I would imagine that The NDC would be more welcome in certain parts of the world than the military in times of disaster. ^_^
