> In a book having a story and then some pages about the historic context, I would expect the context to be somewhat accurate?
Why would you expect that if written by random writer?
> It's also about common sense economy and human behaviour. I don't think humans change all that much.
Your common sense is massively dependent on your values, your religion (or lack of it) and our technology. Humans with different values, different religion and massively different technology function differently.
> Wars and rivalities between cities and between the nobility-dominated land are part of history classes in school.
What you did NOT learned in high school history is how cities, towns and peasants operated in their day to day life. What you did NOT learned was anything about periods in between wars - and most cities were not in constant war with each other.
> Can you bring actual arguments why my reasoning is wrong, instead of simply claiming it just didn't happened this way?
Just about any actual specialized historical book about medieval time, frankly. And frankly, you are the one who made confident claims, you should be able to support them with evidence first.
