We learned that the actions of a people who are engaged in democratic self-rule are, by definition, self-willed actions and by definition not coercive. The self-willed actions of a democracy are no more coercive than your self-willed action to play a game of gin-rummy and adhere to the rules. The self-willed actions of a democracy are no more coercive than your self-willed action to post in this thread and follow the rules of grammar at least to the extent as to make yourself understood. By participating in the democracy, by playing the game, by posting on this thread you have already agreed to the respective rules and agreed to the penalites for not following them.
We learned that neither liberty nor property exist if they are not recognized and respected by those around you. They are man-made notions; neither god given nor woven into the fabric of the universe.
We learned that when interpreted literally rational self-interest is too narrow a notion from which to derive the notions of liberty and property; that when interpreted more broadly rational self-interest is too weak a notion to support and guarantee liberty and property.
