  This tool is for measuring curves drawn on a piece of paper, not abstract curves.

      Well, it doesn't in theory, but it does in practice. Natural phenomena are only fractal over a certain range of scales. Outside that range they follow normal rules.

      That doesn't fit on a piece of paper, either.

        A cartographer might disagree.
