Those are the rules. The application is individual.
Think of Icelanders eking a living out of nearly bare soil in an inhospitable climate, and then think how much the world has profited by selling them useless things like fences. Think of how much land was eroded just to pay for this nonsense.
And then all those profits blown up in wars. Imagine what could have been.
What are fences for?In some countries, fences are to separate herds from grain land, or to divide pasture land, for successive grazing over a season, or just to keep the stock off the road. In Iceland, it’s a bit different. It’s something people learned from the land and tried out.
Now to figure out what is being fenced in, or fenced out! Not these reindeer. They just walk over fences.
Not these horses.
So, like, a halter for the human will!
