Note that you can’t literally homestead anymore…you can’t claim unused government land, improve it, and be granted that land. You can buy land, but the trouble is that 95+% of land in Alaska is government owned in some fashion and not for sale. So the fantasy of owning thousands of acres of wilderness is just a fantasy. You can buy land in Alaska, but it isn’t particularly cheap compared to the Lower 48, especially anything accessable by road.
The reality of bush living in Alaska is often pretty grim. People shooting each other, alcohol, kids huffing gasoline, no jobs, no future, no hope. Of course, that’s bush village life. You’re talking about living in an isolated cabin and only seeing other people a few times a year. Are you really up for that, psychologically? 99% of people just aren’t, even if they could live comfortably in the wilderness most people couldn’t stand to be isolated like that.
And lots of people who try to live that way are really engaging in a form of slow-motion suicide, like that kid from “Into the Wild”. He wasn’t an outdoorsman who made a mistake and paid for it with his life, he committed suicide by wilderness.
And the other thing is, winter. In the interior the first snows start in September, and doesn’t completely melt until May. Sure, September isn’t really winter, and May isn’t either. But are you psychologically prepared for 6 months of winter? Are you prepared for 2-3 months of only a few hours of daylight every day?
Of course, the reality is that most people in Alaska don’t live in an isolated cabin only accessable by float plane, they might live in a cabin, but the cabin has a driveway that connects to a road and the road leads to a village or a town, and they can go in and buy stuff. But then you need to pay for that stuff, and how do you do that? You can dig gold out of the ground, you can trap animals for fur, and people really do make a living as trappers and gold miners. But the gold miners aren’t living in a cabin with a gold pan and a pick axe and a mule, they’ve got tractors and dredges and sluices and high pressure hoses. And to be a gold miner you’ve got to find an economically worthwhile place to mine, and that ain’t easy.
So yeah, it’s possible to “live off the land” but only if you understand what that really means, and what it takes to actually do it. Just building a cabin is a pretty big undertaking if you expect to do it with just an axe and a hand saw.
