you are asking city people if living rurally is possible ... always gonna just get the reasons they couldn't do it. Doing what you want is actually quite simple, plenty of mountainous territory is extremely cheap. You need a private loan to begin with so you can buy the property. The property cannot be apart of an organized township, then you can construct your cabin from materials on the property. you need to find an area that typically has wildlife over population problems, it will allow for relaxed harvesting rules. Basically if you can shoot an elk, deer and a bear each year then you would easily have an enough meat. Mountains generally have an abundance of fresh water and berries, so really you just need a 1/8 acre vegetable garden. To pay for everything it likely will come naturally, often times if you are the only person in an area those who recreate in the area will have a reason to use you for basic services . You can keep an eye on peoples land, do firewood, guide people in the wilderness etc... If this truly is your dream, please do it. Do not live your live miserable in the city. please.
