Abstract
Libertarian punishment theory was initially articulated by Murray N. Rothbard and Walter E. Block. It was broken down into four separate stages. To a great degree, this theory was accepted by Eduardo Blasco and Davie Marcos. However, they maintain it is in need of some slight adjustments and improvements, mainly dealing with the interest rate. The present paper claims their suggestion while valid, is unnecessary, since this theory already incorporates that element, at least implicitly.
