Her reply was that it would be nice, but no one else would ever let me do that. "That's just not the way things work..."
My opinion is that if individuals like me don't leave other people alone (as in not using coercion against them, whether personally, or "collectively" through The State) to do as they wish, as long as they aren't stealing or attacking, why should we expect them to leave us alone? It has to start somewhere.
Maybe that's not how the world is now. Maybe it will never be like that. However, I can still make my own life better- right here right now- by doing the right thing even if others don't. I make my stand on the principles of voluntaryism/anarchism/libertarianism. However that turns out, it is my choice to stand for your liberty, and thereby enhance my own.
