I hate to be the one to say it, but that freicoin manifesto is a cesspit of keynesian gibberish and populist nonsense. Calling it a "comprehensive economic theory" is to go zero for three.
Technically, not keynesian. I'd say it's arguablely a variety of a monetarist theory, although not of the dominate set.
