YOU CAN STILL HOMESTEAD TODAY!!! WILDERNESS and REMOTE LIVING is AVAILABLE in 2017! Although many of the government homesteading programs are gone, the dream of homesteading a remote or wilderness homestead is still very accessible and available. The state of Alaska has many remote parcels available for "over-the-counter-land sales" <=click or paste - http://dnr.alaska.gov/mlw/landsale/otc/
Canada has many affordable wilderness large acreage parcels where you can still homestead today. Many are very reasonably priced and Americans can stay at their Canadian homesteads up to 6 months a year. Dual Citizenship is also available which would make full residency possible. With dual citizenship you must realize that if borders are closed during time of war you will have to remain on whichever side you reside when the border closes. However, I must say that Canada has some of the most beautiful wilderness areas/habitat.
There are still laws and regulations to some degree, but fewer restrictions than in areas of more concentrated populations. That is the essence of wilderness living...Freedom to live, not just exist, but to grow, learn, stretch your mind, and physical abilities, to really LIVE!
