Even if he was a complete putz he was still the friggin' king and why would he decide to skimp on "eternity?" You see, the whole problem with the "tombs and tombs only" reasoning is that it can't survive removal of any of its component parts. It's a house of cards in the respect that you have to buy the whole premise or none of it works.
There is clearly a trend away from pyramids in Egyptian history. Certainly by the New Kingdom pharohs were buried in the Valley of the Kings, and no more royal pyramids were built. I think there can certain be a long transition period when the theological basis of the Pyramid weaken to the point where the king no longer judge the trade off needed to build his pyramid up to Korfu standard to be worth it, but not weaken so much that pyramid construction stops all together.
It is also possible that extravagant construction well fitted and massive pyramids of the 4th dynasty brought about some major political or economic crisis that served as a lesson for later pharohs and warned successors off from undertaking similarly massive undertaking. Once it became clear that labor and cost of building a pyramid can become a source of instability and threat to royal authority, while the imposing edifice of a completed pyramid can still serve to enhance royal and dynastic prestige, then the temptation must be there to cheapen the construction of the pyramid to obtain the most outwardly imposing edifice at the most reduced cost and labour. In this case shabby construction must result.

Post Giza pyramids are largely rubble. Pre-Giza pyramids were of varying types and quality. But the story being put forth by the Egyptologists is Red Pyramid-Great Pyramid-Khafre-Menkaure-Userkapf... and that really runs the gamut in terms of quality. The question is even odder if you extend it on the older end and cite Meidum (which collapsed apparently during construction) and the Bent Pyramid which was an engineering disaster.
With all this, we still haven't discussed ramps and even the Egyptologists can't come up with a satisfactory explanation for that issue.
Actually, it seems to me the progression from Zoser to Meidum, to Bent, to Red, to the Giza Pyramids illustrates perfectly the gradual evolution of constructional technique and progressive increase in willingness to invest. Prior to Zoser there were no pyramids in Egypt. Kings and nobels were buried in single step rectangular mastabas made of roughly shaped stones covered by a smooth casing. Zoser decided to square off his mastaba and stack a series of successively smaller mastabas on top of the first one, thus making the first stepped pyramid. The construction of the step pyramid was essentially 6-7 familiar mastabas stacked on top of one another. Each step remains roughly shaped stones covered in a dressed case. The only major advancements seem to have been:
1. Devising a means to get the stones up to the top of the pyramid.
2. Build load bearing well dressed internal walls into the lower mastaba to support the weight of the upper mastabas
3. Invest a lot more material and labor
Meidum definitely started out as another stepped pyramid, built just like the Zoser pyramid, only larger. In its current state the top 3 steps and the lower retaining wall supporting the 3rd steps still remain. It appears that when the stepped pyrmaid Meidum was nearly finished, the king changed his mind and had the steps filled in to achieve a smooth exterior. Again, increased labor and material investment.
When Meidum collapsed is highly debatable. Arab records indicates Meidum still had 7 steps in the middleages, suggesting the stepped pyramid core inside Meidum remained intact through the middle ages. When the filling that converted the Meidum from step to smooth collpased is also debatable, some sources suggests the collapse happened during the New Kingdom, not during construction. But let's accept the early collapse scenario, granting the filling might have slid off of Meidu during construction. This should teach the Egyptians a lesson about the inadaquacies of simply filling in the steps of a stepped pyramid to achieve a smooth pyramid.
Evidence of this lesson learned is found in the Bent Pyramid. This pyramid was built as a real smooth pyramid, not a stepped pyramid with steps filled in. Trail by error, no quantum leap. But bent pyramid had its own problems. Like the earlier step pyramids, it was made from roughly shaped stone fillings spaces between smoothly dressed internal load bearing retaining walls and external filling. Only bent pyramid was larger than any previous pyramid. Roughly shaped stones are not ideal for load bearing because of limited contact area between stones and internal voids into which stone can deform under load. The inside of the bent pyramid shifted and cracked, evidence of the internal subsidance can be seen inside the chambers of the bent pyramid. Bent pyramid made it clear that Eqyptians were pushing the limits of how big pyramid filled with small roughly shaped stone filling and steep external side can get before the rough stones crush under overlying weight and the pyramid subsides internally. The Egyptians again appreciated the steepness issue right away and tackled it methodically. First they reduced the steepness of the sides of the top of the bent pyramid, thus reducing the top load inside the bent pyramid. Second they built the next pryamid, the red pyramid, with reduced steepness. But appearently they also appreciated the structural weakness of using poorly dressed dillings between well dressed walls. Hence the great pyamids of Giza with their well shaped, load bearing filling stones. Again, trail by error, accompanied by increasing investment in labor and material.
It seems to me the pyramids preceeding the Giza giants illustrate without even a missing link the systematic progresses the Egyptain made that brought them from Mastabas to the ultimate form of pyramid construction.
