I think you're missing the point.
The benefit from the Pyramids isn't caused by the Pyramids themselves. (After all the Pyramids are just piles rock. They don't do anything.)
The benefit comes from (and represents) having an early government advanced and powerful enough to be able to pull off such a huge undertaking.
A central government as powerful as early Egypt's was a radical new developement in the ancient world.
It is entirely appropriate that the benefit that goes with them is related to government.
