The thing that I hate even more about all this, I could afford to do this. But you are not legally allowed to live on your own land in the UK without planning permission. I think it is vaguely comparable to zoning in the US.
We still have parts where you can disappear into the woods and just sort of fuck off forever. Alaska has the Remote Recreational Cabin Site program as a replacement for the Homestead Act and there's parts of the state so remote you could essentially do whatever you want and nobody would ever know. Provided "whatever you want" involves freezing in the dark wilderness.
I'm sure some of our other low-density states have similar things going on, and zoning laws vary wildly.
Hey hey hey, the wilderness is only dark in the winter and you won't freeze to death if you don't get wet and are wearing modern winter coats+snowpants+gloves.
Thats what i love about Canada, you can buy land in unorganized townships and can do whatever you want there. The interesting wildlife is just the icing on the cake.
