Pretty easy, and superficially appealing, but I find that there must surely be exceptions to a rule such as this. Nuclear weapons (and similarly, some chemical weapons) are the obvious special case.

Edit: reminded reading a comment below that child pr0n is another one that the general moral consensus has problems with (I refer to the 'consensus' not because I think it is always correct but simply as it provides cases worth thinking about), and also handling stolen goods (although this can be justified through property rights).

Seems kind of like the "Godwin's law" of rule of law. The fact of the matter is that we simply don't encounter these sorts of situations often enough for myself to understand using them as policy setters.
