Because somebody claimed that you can't have organized society without banking, while for a long part of history there were organized societies without MONEY.

Well, yeah, now I understand.

You can definitely have organized society without banking, but AFAIK there was no organized society without some form of taxation, and few organized societies without long-distance trade (only in isolated places).

Taxes can be assessed as a percentage of production and collected as goods rather than collecting money amounting to the value of those goods.
