This is just imprecise statement of principle. It's more like you're against the government intervening unless they're credibly doing it to save lives. If someone discovered how to turn a microwave into a nuclear bomb, presumably you'd support government intervention to collect all the microwaves, even if they had to intervene a lot in our lives. Likewise, you support government intervention to reduce covid deaths, etc.
Sure, you could just say that your “principles” are simply the entire exact sequence of actions you take in your life. That way you could by definition never change or violate your principles.
But usually people use “principle” to refer to a relatively concise statement that can be applied to a large variety of situations.
I just mean that it must be more concise than a lookup table from every possible situational input to the recommended output. The same is implied by the term “explanation.”
