I think Mises understood natural law, but was weary of anything called “natural law” because it was usually disguised socialism/“social justice.” Mises is essentially saying that people don’t have a right to anything (a car, house, healthcare, et al.); but again, this isn’t the version of natural rights I support. This debate is a semantical issue. I recently sent Jesse and email and he agreed with everything I said, but refused to call it natural law.
