I honestly feel the opposite way, I think if you want to make a really tall tower and you don't have modern engineering and materials to help your narrow towers stay standing, a pyramid is the natural thing to build. There's a reason multiple different cultures built them independently.

The blueprints were super easy for the aliens to explain

To be fair I'm still not entirely sure how they designed the interior; did they cut into the pyramid after it was built, or did they have the interior built at the same time or prior to finishing the construction? It feels like the pyramid would have trouble being even-sided on the outside when the interior isn't a perfect square all in all.

Also on a further note on how awesome the pyramids are: apparently the bricks are 'stapled' together; that is, they dug grooves into the tops of the blocks and then poured molten metal into them to hold them together; that's pretty cool to be honest.

They did in fact build obelisks. Thing about obelisks is that what topples them isn't shifting soils or wind or water, but humans who are looking to alter the slate of history or remove something they feel opposed to.

The labor to knock down a tower is much less than the labor to flatten a pyramid. This is the main selection pressure that leaves pyramids in place.
