Besides any other consideration, I don't think that I really much care for your tone ...

(Who portrayed them in that way?)

There are numerous different proposals for how the pyramids were built. If you look in Lehner’s “Complete Pyramids”, I’m sure you’ll find pictures of different types of ramps, which all have pros and cons. I don’t know whether Lehner has a particular favourite amongst these, although, like any good scholar, I suspect that over time he’s changed his views.

However, that’s totally irrelevant to the subject: i.e., the reason for the location of the subsidiary pyramids.

Whatever method you use for piling the stones up, you still have to get them up to the plateau. Even people who don't agree with the theory that ramps were used for piling the stones up accept that there were supply ramps to get the stone to the base of the pyramid. The south side was the only option. See this, which gives all the necessary information.

So, going back to the original question:

The subsidiary pyramids were built where they were because immediately to the north was Khufu’s causeway.

They couldn’t be built to the south, as that was the location of the supply ramp to get the stone up.
