When I lived in WY I did a lot of hiking/hunting and minimalist camping. Living in the woods can be done, but you need practice.
Try camping with a tarp, some cord, a wool blanket, a decent knife and a light firearm for a few days first. You might be miserable, but you’ll learn more about what to do with less and making do.
As far as food, it depends where you are. I camped minimalist for most of the summer in 1998? 99? in the Tetons, took a salami and tortillas and lived in the Granite Peaks area for about three months. There were so many of these grouse type birds to be had, I never needed other game except for a change. They were also eating some ground berries I couldn’t identify, I figured, good for the grouse...and added them to my diet.
I didn’t lose much weight, but the nights were cold above 9.000ft and whetever I went I stopped early to get plenty of firewood because even in summer nights were frosty. I would try to find either fallen poles to wrap my tarp around or living young trees I could trim some branches and bend together to make a 2/3 tipi with a fire in front. I brought a crank radio, and the funny thing was the only station that came in clear was one on the Crow (I believe) reservation nearby, so it was quite an atmosphere when they were playing traditional music.
I could probably have survived quite a while, except winter was coming. I did a lot of experiments building shelters and I suppose surviving up there was possible. I would rather have had more food, flour, oil, coffee, etc. ...and the thing I missed most was hot water. If there had been a hot springs to soak my bod in, then I could very well have said “screw civilization” for a year or more. Bathing in a creek that was melting snow five minutes ago is doable but it ain’t fun.
Anyway, go ahead and go camping “survivalist” style for a few days. You’ll learn something, regardless. Or, you could do like I did. I bought a fixer-upper cruising sailboat and moved aboard...live in a tropical climate...and when I “bug out” my home is my escape shuttle. Best survival platform I know of for the few thousand I invested in it, and the cheap living served me well in this economy.
But if the ocean’s not for you, I’ve lived in ID, MT, CO, and WY and while there are similar attributes I think Wyoming has certain advantages for either a home redoubt, or, if you truly want to disappear, and you can survive in the mountains, if you stay on the move you can pretty much stay ahead of any govt. agency that tries to find you. There are fugitives living in the Rockies that the FBI has been after for decades, and tbey know they’re alive, because they pop up in mountain towns here or there for supplies and then disappear again.
Anyway...I like the sailboat platform. I’m in a river now where wild pigs show up on the shoreline, ducks come right up to the boat and dizzy geese have actually collided with my mast stays flying at night. And there’s always the “escape to the South Pacific” fantasy lurking in the back of my mind. Keeps me buying extra beans and rice at the store and stashing it away, just in case.
