Well, that's an interesting question that I haven't thought about like that, and I am happy that you bring it up....
I guess the biggest change that you experience in those cases is the sudden lack of personal possessions, since you can not carry them around. So, all those things that seemed life-basics back home now they become superfluous. And the best thing is, after very little days you don't miss them anymore.
So at least, nomadic people learn to live happily with less, and to value what is necessary and what is not to live with satisfaction. I guess if somebody is too attached to their possetions, wouldn't be able to cope with a lifestyle where you just have what fits in your backpack (or other carrying-mean). But this same people can learn to loosen up this attachement by having a taste of this lifestyle.
People who adopt a nomadic lifestyle coming from a western background, these days, show, first, a disconformity with the system they have been put in, and a brave try to go further away the bubble the machinery of society tells you must fit. It is of course impossible to totally escape this system, and I guess it is not any option that lets you step fully aside, but symbolically is what comes to me.
Keep it up!
