Well if you read it you failed to understand it, because it clearly discusses barter systems relating to debt, not currency.

Your refusal to understand the difference between bartering and money is making it impossible to educate you on why you are wrong. Debt is not money, bartering is not money, they are different concepts.
They also didn't have currency.
Do you know how I know you didn't?
Anarchist societies didn't have currency. They used bartering.
Yet you keep acting like it. Currency came well after governments, because you need a government to regulate the value of currency and give it stability.
Bartering existed before currency, perhaps you're thinking of bartering and confusing it with the idea of money. They are not the same thing in case you weren't aware.
Ah, cool. So weed is money. Understood.
Here you go, government evolved with agriculture, and predates currency:

Also your book doesn't say currency predates government.
Why do you think modern governments are the only type of government there has ever been? Tribal governments, elder councils, feudal governments, republics, pharoahs, god-kings, etc... Ever since people have lived in groups they have followed some sort of governance.
That tribes have governments? Yes, it's called tribal governance. Literally any power structure dictating the lives of a group of people is their government.
You think that governments didn't exist thousands of years ago? Governments predate debt and money, by a long shot because guess what, ever since we've been tribes we've had governments. A tribe is a government.
Nope, not the same thing.
