One thing I don't see in most of these plans are ideas about what other members of your group are doing.
One of the things that makes humans effective competitors with other species is our ability and willingness to co-operate to achieve a goal.
On person might not be able to kill a bison, but 10 people can slaughter a herd of bison and turn a bear into a nice rug.
It is the same for making a camp or plowing a field.
One person can only carry enough gear for the barest of existences.
10 people can carry enough for a decent chance at having some sort of technology.
Then there are the skills and specialties. You might want a skilled forager and a skilled herdsman as well as a skilled cultivator.
If you are really proposing living just off the land you will need a community that can provide a bit of support to the members of it.
