Consider what rampless literally means. Well it means “no ramps” and if you were a Pyramid builder and knew a rampless method for construction there may well be many advantages.
Ramps are not mentioned in the ancient Egyptian records so why mention ramps here. Simply because in the last two hundred years various ramp theories have been invented and have persisted to the point of becoming world consensus of how Egyptian Pyramids were constructed.
Rampless Egyptian Pyramid construction by the ancient method is fully explained with a firm style aided by photographs and colour illustrations.
