Thank you for giving another example along that continuum. I admit that your example is in that gray area, and I have a hard time giving a definitive opinion on it. But, to reiterate the point: that does not proof that all such hypotheticals are undecidable. Imagine someone stealing 1 cent. Should they go to prison? Of course not! Now imagine them stealing 100 million cents, i. e. $1 million. Should they go to prison? Of course! Just because we're both going to have hard time saying which single cent of those 100 million made the difference between something to ignore and something to punish does in way mean theft should be legalised. And yes, changes in efficiency do matter. That's why even the US does not recognize a right to privately build, own and operate nuclear weapons.
