If I had to build a pyramid in the desert 4000 years ago, that’s what I’d do. The alternatives would be a big bother.
No, no the quarryies are fairly clear for many of the pyramids - at tleast those near Giza to actually quarry and move simple rocks.
BUT!
It seems that it would be far easier, far cheaper and faster, to actually quarry and move the outside the rectangle blocks as two layers of rock , and the line the internal hallways and tunnel rocks of the central ramps and burial rooms. Then fill the rest in between with chips and small rocks and irregular rocks and sand. The outside layers form the shape and retain the loose rocks and sand inside the visible walls.
The problem with the rubble fill idea is, the interior of the Great Pyramid is known to be made of blocks thanks to probing, drilling, and the Robber's Hole, which was chipped up through the structure, probably since the muzzie takeover in the 7th c.
Rubble fill is another suggestion that many Egyptologists dislike.
