Yeah, taxation isn't extortion and tyranny isn't representative government tho but otherwise agreed!

I would argue the conversion is the one you're utilizing, from "taxation" to "extortion."

Extortion is a specifically defined crime, and of course, it is the role of the government to define criminal behavior. In the same way that getting arrested by the police isn't kidnapping, paying taxes isn't extortion.

The consent of the governed and all that.
