The problem with that logic is that Trail Markers are accepted. Moving along a trail to get from Marker A to Marker B, isn't different in any way shape or form from moving along a trail to get from Rest Stop A to Rest Stop B. Same truth for explore criteria.
Trail makers represent the part of the trail they are on. They are not in themselves eligible. If I take a trail marker off the trail and put it somewhere else that isn't part of the trail, it loses its status as a Wayspot.
