You can take a kill to a butcher. You can drag an elk out with a ATV or other means than relying on your own strength, but some can do that as well. You don't need a truck necessarily, an elk can be quartered or de-boned in the field. A bone saw is helpful, but it isn't necessary.

Millions of Americans hunt for deer and elk without a lot of the gear you list.

Hunting isn't some sacred thing that can only be accessed through special means, even though plenty of hunters frame it as such. You can pass a hunter's safety course in less than a week, while learning the basics as you go.

However, I agree with the idea that using legal hunting as a means to survive during a national food shortage is grandiose.
