Please confirm that my understanding is correct. You have a number of "stupid" terms in Lagrangian, whose cumulative effect must be small in order for the whole theory to make sense at all. This small cumulative effect can be achieved in 2 ways: 1) each term is small 2) terms more or less cancel out. When each term is small, we call it naturalness, otherwise it's fine-tuning. If this is correct, then... say you have N random varaibles, and you know that the sum is small. What is more likely: that each of N variables is small, or that the sum is small because it just happens to be small? :)
