My rules is, If you're not surviving the way you're living now, don't plan on it then (e.g. SHTF.)
Conditions, competition, etc will likely only be worse if you're having to "survive." If you're not already supporting yourself
gardening, hunting, etc, it's very unrealistic to think you'll pick up the skills and bring in enough when the time comes.
It makes more sense to develop these things now, and become as self-sufficient as possible without waiting for
something bad to come along and force you to do it. In the meantime, you'll have the benefit of new skills and
savings from them that makes you able to store that much more with your money.
The old adage of train how you fight, fight how you train comes to mind. Maybe updated to
"live the way you would like to survive, survive the way you would like to live."
