I lent out my copy of the Dawn of Everything so I can't get exact quotes or pages but this reminded me of a point in the book (which I highly recommend) which I'll attempt to summarize:

Domestication of plants was "easy" when tested in a controlled setting selecting seeds carefully at a university. Estimated that wheat in the agricultural "revolution" (a much scoffed about term in the book) could have been domesticated in 200 years if purposeful. Instead agriculture took something like 3000 years to become dominant versus mixed food sources (mostly gathering, fishing and hunting, with some low-effort planting on riverbanks).

And yes to your point, the idea that there is some sort of progression in human societies is contradicted by the recent decades of evidence in archeology -- every arrangement you can imagine seems to have been tried (stationary+hunter/gather, nomadic farmer, alternating back and forth, shifts toward farming for hundreds of years and then back to fishing for thousands). Humans time on the earth has been much longer than our recorded history, with more variety and less boring than we usually assume.

Anyway I hope that inspires someone to pick up the book, it really is a good read.
