Private property is a most sacred right of mankind

Adam Smith writes in The Wealth of Nations:

To prohibit a great people, however, from making all that they can of every part of their own produce, or from employing their stock and industry in the way that they judge most advantageous to themselves, is a manifest violation of the most sacred rights of mankind.

This quote reminds me of what John Adams wrote in 1787 in his A Defence of the Constitutions of Government of the United States of America:

The moment the idea is admitted into society that property is not as sacred as the laws of God, and that there is not a force of law and public justice to protect it, anarchy and tyranny commence. If "Thou shalt not covet" and "Thou shalt not steal" were not commandments of Heaven, they must be made inviolable precepts in every society before it can be civilized or made free.
