"Force is a necessity for protecting property, as men will attempt to steal property. You don't "protect" your property with labor. You justify your claim of ownership by proving that you have labored for the property, but it doesn't "protect" property. An individual is justified in claiming ownership of property if he obtained said property under voluntary means, either from homesteading or trade. "
No you don't protect your property with labor, but you establish your right to protect it with labor and you lose that right when you abandon your labor.
In other words no one has a right to something they did not earn.
