The law that’s absolutely supreme, inescapable, and eternal is natural law.  We can only have justice if natural law is followed.  You are free to act so long as you don’t interfere with the rights of others.  We are at peace if this is fulfilled.  We are in perpetual conflict if we don’t follow natural law.  Natural law doesn’t allow force or fraud.  Therefore, one must live honestly and not physically harm another.

It’s certainly civil to be moral, but its not legal to do so.  Manners are important, but they do not fall under natural law.  For instance, helping those in need is moral, but not helping isn’t a jailable offense.  It’s a legal duty to not physically harm those in need.  Morals must not be grouped under natural law.  Not helping those in need may not be accepted.  Legality and acceptance are very different.

Each individual is free to associate or disassociate with anyone.  Freedom of association falls under natural law.  This freedom can be followed for any reason so long as there is no wrongdoing and actions are taken voluntarily.  A group of individuals can’t be coerced into associating with those they choose not to.  Association is dependent on each individual’s interest, judgement, and conscious.

No individual can be required to support another group.  This support can take any form.  The individual can view the support as absurd—for any reason.  Forcing one individual to support another individual or group is criminal.  The reason for the support doesn’t matter.  Force is required and its a violation of natural law.  Each individual has the liberty to support and associate with any group they please.

Natural law is necessary to maintain justice.  Do you want peace or perpetual conflict?  You want natural law if you want peace.  Natural law is something every child learns at a very early age.  The parents will tell their child: don’t hit or steal from the other kids.  The child isn’t taught that he has arbitrary control of others, or he can make rules others have to follow.   However, this is unlearned through years of propaganda.
