Are we all soldiers or police in our society? No, because there are lots of other jobs, essential jobs, that do not require the use of violence. It may also be the same in a survival situation. Extra manual labor might help, if your plans are flexible enough to benefit from it. Look at the division of labor in Stone Age societies: only some wield arms. There is plenty to do in the village.
You're not going to be in firefights all the time, or even much of the time. If you're going to be shooting thousands of rounds, you're probably fighting a better equipped, better supplied army, and you'll die anyway. But even in a firefight, there are things that non-shooters can do to help, like loading your mags/clips.
With that said, if you have the funds for some extra guns, why not? We're INGO after all!
