Is the 7 inches absolute, or distance apart? As in, could I teleport past a 7 inch thick wall, or just 7 inches from my current position? If I could get through the wall, that miiight be more abusable. Otherwise totally the gravel. Even if it doesn’t magically appear, gravel is useful for all sorts of stuff. Especially if you get to pick what type/grading/etc each load is like with purchased gravel. That’d be really useful.
