This hypothetical is utter nonsense. If you weren't helping hitler, he would send his storm troopers to arrest you, then do what he wanted anyways. There's a reason godwin's law exists: people think that invoking hitler is an argument cure-all, not realizing there's a reason why hitler is considered a uniquely bad person.

We pretense to live in a "free society". This refers to one where each person is allowed to do as he pleases, as long as he isn't interfering with another's right to do the same. The concept of "utility neutrality" can only exist within such a society, but more importantly, a free society cannot exist without such a concept. As long as there are laws preventing a person from misusing utilities, someone's use of a utility can never be an attack on another's freedom: before that occurred, they would be arrested for breaking the law. On the other hand, people rely on access to utilities for heating, for cooking, and more broadly for survival, let alone necessary for that pursuit of happiness supposed to be crucial to the american dream. If a person's utilities can be cut off arbitrarily, then naturally this can be used as a punishment for their behaviour or identity; their person, in other words, is no longer free to do as they will. If you cannot see how this is exactly a step towards hitler's dystopia, then there is no helping you.
