But why bury people's bodies at all? The whole purpose of cemeteries as physical spaces is to honor the deceased by literally sacrificing land in their memory. Without the sacrifice, why not just have virtual markers located around town and cremate or compost bodies? Obviously the answer is that some religious traditions prescribe burial, but this also answers why your original design is inadequate.

Do those religious traditions that prescribe burial also require physical headstones instead of virtual ones?
