I'll propose this as the only unbreakable law: "everything in moderation", which I feel implies any law is breakable, which now this is sounding like the barber's paradox. What else does anyone propose as unbreakable?

>> everything in moderation

Saying this is like saying 'pick the optimum point' without saying anything about how to find the optimum point. This cannot be a law, it is the definition of optimum.

Note that optimum point need not be somewhere in the middle or 'inside', like a maxima. The optimum point could very well be on an extreme of the domain (input variables space).

Counterpoint: "everything in moderation, including moderation"
