I am constantly moving to whatever area I feel best fits my needs at the time. The vast majority of my financial dealings are in cash. I live off the services I can provide, such as landscaping, childcare, elderly care, or tutoring. I have lived in tents, on couches, in RV's or whatever works at the time. I even finished my college education like this (I know, I know... college is bad, but I wanted a degree so I got one and I paid for most of it in scholarships and cash).
I will admit, I am able to live like this because I am young and I do not have kids or a family to consider. That being said, it is a great way to exercise freedom, and when I don't like the area I am in any longer I move on.
