Well, sure you have to keep your options open.
I'll poke a different set of logic:
When you are "mobile", you are dependent. Dependent on an economic system that is at least semi-functional, assuming you haven't turned into a pirate. You depend on finding shelter, food, heat, etc. You cannot produce ANYTHING yourself.
When you are in a stationary point (and well established) with some acreage you PRODUCE. You PRODUCE food, you produce shelter, heat, etc. You have the means to survive w/o an economic system. Now you may find yourself face to face with some of those pirates, and things may not end up going your way. At best you end up a nomad (or "mobile"), worst you don't have to worry about it anymore.
But if you don't have that land and can work it, you aren't playing farmer on a 1/4 acre lot in suburbia.
