As someone who actually hiked that trail: I think the author is just missing the point: yes the whole system could be improved, that´s correct, but that´s not IMPORTANT! Collecting the stamps is just to motivate people, give them a feeling of accomplishment. You can opt for not getting a single stamp, but collecting them is just part of a tradition, which has it´s roots way back before the socialist era. Also note: this is whole thing is jut run by a bunch of volunteers in their free time, and they for sure spend their own money to do so. BR W
