Is it ever a good idea to print money?

I think you are ignoring the fact that private property was as central to Mises understanding as to Rothbards.

Economics is the study of human action. Human action is based on both natural and man-made law.

Natural law is nothing more than hard science in relation to biology, physics, chemistry, etc.

Man-made law is a fairly arbitrary concept that changes and interacts differently. You could say economics incorporates that, but that isn’t economics in its own right.

You never read the theory of money and credit.

Neither of those changes the fact that human action is based on natural and man-made laws.

Esuric,

This is my answer.

Yes, but, I’ve already explained why that’s wrong. I suggest you read the theory of money and credit, it would cure you of your confusion.

I don’t think you could explain why you’re even continuing this.
