Don't Move Landmarks and beyond

Thou shalt not remove thy neighbour's landmark, which they of old time have set, in thine inheritance which thou shalt inherit, in the land that the Lord thy God giveth thee to possess it.

These are from multiple denominations and different translations but it is interesting to see how the slight word differences work. }

So much was covered in this short sentence...

First is the obvious literal translation that says don't take your neighbor's property... and it starts with land and who is entitled to the land.... but it goes much farther.

This is later extended to include any type of encroaching on another's domain. Intellectual property is included and thus it is the basis for copyright laws and possibly even ethical laws relating to unfair competition.

This is one of the more serious commandments as it is included in the 'big 10' in several ways: Do not steal, Do not covet are both included here.

This ethics code extends into today in many ways... and the bottom line is that we are not to encroach on someone else's personal property or their livelihood. It is a strong statement of the integrity of the self.

This is one of the laws that makes us realize that the Torah is teaching us how to set up a just society that is mindful of the rights and obligations of individuals.

A related reference on this is in Lev 25:23 'The land shall not be sold in perpetuity, for the land is mine; for you are strangers and live as foreigners with me.' - noting that the land doesn't belong to individuals it belongs to God... there are places where this is practiced - including in Alaska and Hawaii where the land is not sold.
