If one wants to move a tree, then "yes". If not, probably not. I've taken a medium size (about 11 years old at the time) out of the ground before. I used the last method I wrote about. It was a pain in the butt. While most of the roots will be in the top 8-12" of soil, inevitably, there will be a few roots that grow downward. Either one would need heavy machinery to sever all of the roots below the tree then to pick it up out of the hole, or one would need to bare-root the tree in situ.
The nice thing about digging sections is you're not committed to too much. If you start to dig and you get tired, bored, lose steam, break a shovel, step in a fire any mound, etc. You can fill in what you've dug, then start again there in a few days.
Here are a few pics of the prep I did to remove a tree from the ground.
