What a pile of nonsense.
Capitalism is the natural result of respecting basic human rights. The right to own your own property (including yourself), the right to exchange what you produce freely with others in a mutually voluntary way, etc. "modern monetary theory" is simply the latest iteration of people who have no actual grasp of economics trying to come up with fancy-sounding reasons for why their terrible ideas aren't REALLY terrible.
I am not property!
The concept of self-ownership is neither innocent nor natural, but rather is part of the foundation of false narratives that capitalism is built upon.
"... the right to exchange what you produce freely with others in a mutually voluntary way..." is NOT capitalism!
