No, I'm not. The Great Pyramid was built circa 2500 - 2600 BC, or about 4600 years ago. I think it's fair to say that civilization was humming before that, and that even the construction likely attracted tourists. Seems to be part of the point of monuments.

Djoser's pyramid seems to have been completed around a hundred years prior to that, and would have drawn crowds sufficient to warrant the large temple, grand entrance, and colonnades which are part of the complex.

There is a great deal of evidence that offerings provided by people traveling to these complexes sustained the religious orders on site who provided guardianship, maintenance, and worship. And that this was planned as part of the construction.

Djosers pyramid has an inner chamber that is suported by massive cedar timbers hauled from Lebenon.....and we have the Epic of Gilgamesh which details the triumph of Gilgamesh over humbiwaba the forest guardian, and harvesting and transport of cedars from Lebenon, we also have the commercial records of the mesopotamians trading activities over vast distances and time periods, and so it is zero surprise to find that "the black haired people" also left there genetic's with the rest of the cultural, linguistic, and mythical baggage that we are consiously or un consiously hauling around, still.

The tomb and temple complexes aren't built to accommodate demand. They're built at the size the king wants them to be, and used for official ceremonies.
