: : Arent there a lot of crimes that have nothing to do with property or property relations?
: The idea of natural property. You own your own body and mind. direct attacks against your person are crimes against your body/mind. There are some (eg supporters of conscription, national service in other areas) who oppose this idea, and lay claim to your person.
If you 'own' your own body then it stands to reason that you can deal with it as you deal with other property, ergo i can sell myself into slavery and have the 'property' of my body owned by another.
Attacks against your body and mind can be 'crimes' without invoking the notion of property. For instance on the basis of morals or on the basis of social utility.
