Steve, my understand is that no one is stating that a center core tower gives better structural integrity to a pyramid. From my armchair, the issue is that at least some pyramids started out as a simple core tower as their end design, but then the outer skin was added as a later project to render the true pyramid look.
That said, I do believe that adding the outer skin could add a certain benefit to a step pyramid, but I have no idea what the thinking could have been in the case of a central core tower like we see at Meidum which was a disaster waiting to happen.

Since it's not clear that the E2 and E3 phase of Meidum would have been included by a knowledgable engineer in the design of the original core tower, I chalk those outer skins up to adaption by a later, more engineering-challenged culture.

And even if a pyramid only had a dozen multiton blocks, the builders would still be able to justify the construction of a causeway, regardless of whether there also was filler with sand, marl, rubble, small blocks, etc., used in the construction.

How can any of us ever know, when all we can do is think?
