The one (intrinsic) rule inherent to a (free) society has already been codified and developed by the likes John Locke and later classical-liberal thinkers
The one rule that matters is - non-violation of private property
The one definition that matters is -
Private Property: Everyone is the proper owner of his own physical body as well as of all places and nature-given goods that he occupies and puts to use by means of his body, provided only that no one else has already occupied or used the same places and goods before him. This ownership of "originally appropriated" places and goods by a person implies his right to use and transform these places and goods in any way he sees fit, provided only that he does not change thereby uninvitedly the physical integrity of places and goods originally appropriated by another person. In particular, once a place or good has been first appropriated by, in John Locke's phrase, 'mixing one's labor' with it, ownership in such places and goods can be acquired only by means of a voluntary – contractual – transfer of its property title from a previous to a later owner.
The right to life, liberty and pursuit of happiness and fundamental speech, right to arm and everything else derives from non-violation of private property.
