The idea that people cannot transfer to government
powers they don’t have is itself a moral one, and
and moral sanction such as you say governments can
impose is involved in interfering in what some might
call some natural law of the jungle.

the management of resources and imposing as routine
those procedures discovered to be most helpful,
are certainly proper government actions even by your
Randian theory, since resources are often not owned
by any individual.

The theory of government in St. Paul’s epistle to
the Romans is much superior. It is, that government
is an institution created by God to limit evil and
secondarily to reward good. Not that it always does
so, but you can see that the direct beneficiary
is God and as one prophet or in the psalms somewhere
says, when God’s rules are enforced by the king, the
people are happy.

This is not the same thing as divine right of kings.
Indeed, it would be a rationale for coups and
revolutions if necessary, but only as a last resort
since St. Paul said that sedition is one of the
works of the flesh, and sowing to the flesh reaps
death.
