>>All legal concepts are government created fictions.
This is often the diverging point between a libertarian outlook on the world, and an authoritarian one.
To the Authoritarian all laws are just social constructs created by governments, thus it is all subjective and there is no objective truth or unethical laws
To libertarians like myself we believe in the Lockean concept of natural rights, where by laws and governments are erected by man to protect those natural rights and any government that goes beyond that goal is Authoritarian and unethical.
To summarize Frédéric Bastiat "The law is the organization of the natural right of lawful defense. It is the substitution of a common force for individual forces. And this common force is to do only what the individual forces have a natural and lawful right to do: to protect persons, liberties, and properties;"
Ethical Governments are formed to enforce this law, these natural rights, to provide a common defense force of a persons natural rights.
Ethical Governments are not formed to control and regulate all aspects of society at all levels and on all subjects
