When something is dragged on a specific surface the primary determinant of friction and loss of efficiency is weight. When pulling a load up a very steep slope most of the weight is on the rope instead of the bearing surfaces which GREATLY increases efficiency. Much of the work to drag stones up shallow ramps using teams of men is all the work necessary to lift the men and the equipment to drag the stone. ALL of this inefficiency is eradicated by having the men work from a level surface.
But most of the inefficiency of dragging stones up shallow ramps is... ...drumroll... ...you have to build and maintain enormous ramps. They must be two way since men at the top need to get down and the slower teams go the more teams you need on the ramps to achieve the required flow of materiel. This means that the ramps have to be even bigger to accommodate so many workers unless they are running up the ramps.
It isn't very important that ramps are inconsistent with all of the evidence. What matters is they are inconsistent with logic. It is simply illogical to try to build a straight pyramid under a mountain of ramps. It is impossible to build it straight under these conditions and it would have been supremely inefficient. The fact that we believe they had no other technology is simple nonsense in light of your theory and the physical evidence.
Where is Egyptological guidance on this?
It is obvious that a cladded pyramid could only have been built with your system or some similar system. There is really very little question about this. They mustta pulled stones straight up tghe sides and until there is evidence to the contrary this is state of the art. Egyptologists won't even talk about ramps any more it would seem but this doesn't change the fact that we now know stones were almost certainly pulled straight up the sides.
