The ramp already provides mechanical advantage. You don't have to lift the stone straight up.

Mechanical advantage spreads work out over time or distance and increases total work. It is counterproductive when the work required in a small space or short time is already intense. It is also counterproductive when it is grossly inefficient such as having men having to lift there own body weight over a great distance (altitude). It is counterproductive when the work to set up the contrivance is onerous or unnecessary. It is counterproductive when it is even less efficient that the means at hand. Mechanical Advantage can also be misapplied in other ways and often is.

Simple methods are usually the easiest and this goes a million times over (2 1/2 million really) when building a pyramid. But it is also true when dragging 100's of thousands of tons of stone and overburden out of a quarry. They would have used the simplest method of doing every big job because this is the way they thought and because nobody ever wanted to do more work than necessary.

Mechanical advantage is great when you need to lift an engine out of a car but not when you want to assemble a car from its parts.
