Historically, pre-renaissance, the government did not interfere with the economy at any meaningful level, beyond tariffs and taxes, and the odd land reform. This was because
A. The various economic schools had not been developed, and there was no alternative to decentralisation
B. There seemed to be no need to interfere, as the system appeared to work fine, today's industrialised economies, with vastly higher levels of production and efficiency, were not around at that time, and the people were happy.
C. The concept of the state providing services was totally unknown. The first instance of what we might recognise as social democracy was the Islamic Caliphate, Zakat, but as modern medicine and technology was not present, this was of limited impact.

So therefore, EB making the government provide all these services (School/Blacksmith/Healer etc) is historically inaccurate, as the state wouldn't give a rat's ass about the infrastructure of the country, except in the case where the millitary would need to use those services (E.g. Roads). Ofc, the local cities/towns might decide "Let's build an aqueduct", but there was very rarely any state intervention, with money being collected into the treasury almost never finding it's way back into the hands of the poor.

This gives me an idea for a mod; Oeconomia Barbarorum! An Economically accurate modification of Rome: Total War!
