Property is defined as your life and all the non-procreative derivitives of your life. Children are not our property, they own their own lives. Primordial property is your life, body and brain. Secondary property are the tangible things we own. Property in the law usually means secondary property.
Primary property is everything in between our life and tangible property.
Liberty is a primary property right, it is our right to own and control our moral actions. Our thoughts, ideas, talents, skills, work, labor, these are all forms of primary property. Now that we know what property is, we can define freedom. This definition is a very positive definition for freedom and is theoretically possible to attain. This definition makes freedom a product and not a cause.
