We have trangias too, but they need fuel, and fuel's a pain to obtain and carry. All very sound 'stoves' but not as flexible in use as the Hobo. The Hobo stove takes whatever you have available, from twigs to dried grasses, paper to pinecones, and it works remarkably well. Besides, it's fun to make, to innovate, to play around with different configurations. To compare and to quietly be chuffed that your idea worked.
