i've led a semi nomadic life, moving a lot, and even living out of a backpack for a few months and traveling, living on the road, no home. it's fun, it's cool, but it can wear on you after a while. I think you can definitely do it, but it would be easier if you were doing it as a group or at least with one other person. we humans tend to be social animals, and while many of us live our lives solo, the ones who are alone for a looooong time tend to be a bit...off. we tend to want community, and that is difficult when you are a nomad. the only downside to living a nomadic lifestyle would be the loneliness. this is assuming by nomad you mean on your own.
of course, the bedouin are nomadic and they do quite well. they pack all their shit and move as a group. it works for them.
