The truth is most of these stories are unrealistic and very, very short term, aka the first 6 months.
By then everybody who didn't have a plan or take action is dead, and the people who did will organize, militarize, and quickly form at a minimum a feudal system.
What is MUCH more likely is the new militerized city states will start warring with each other, with a conqueror emerging who forges the first kingdom.
