It's very tempting to try to reason things through from first principles. I do it myself, a lot. It's one of the draws of libertarianism, which I've been drawn to for a long time.

But the world is way more complex than the models we used to derive those "first principles".

It's also very fun and satisfying. But it should be limited to an intellectual exercise at best, and more likely a silly game. Because there's no true first principle, you always have to make some assumption along the way.
