I'm not sure what you are looking for. OP linked a cashless society to being the cause of government control. This is false. Government can exert control already in a cash-based society to a sufficient degree. It's more a style of the government in question than the tech used.

You missed the part where I said a government id is required to make a purchase, so there is a single point of failure aka disconnection. This is not true in the USA or other countries where you can have cards from many different banks so if one blocks you, you pay with another. And cash certainly represents a way of paying with no such restrictions.
