Arguably the worst part about “roughing it” is going to the bathroom. No one wants to squat behind a tree, the idea of using leaves is horrifying… it’s all sorts of bad. This person had a solution to this problem – bring a toilet ring and build a toilet!
One has to assume this brings more issues, though, because “it” has to go somewhere. If you look closely, it almost appears to be a “real” toilet surrounded by rocks (you can see the white in the inside), or perhaps a hidden-bucket situation. It seems like you’re asking for a lot of problems, with this.
