Exactly, and the reason for this is that we can't cover all possibilities with enough granularity for black and white to be close to reasonable.
If it was illegal to break a lock (black and white), then the guy who breaks a lock to steal your TV gets the same sentence as the guy who breaks his own lock because he forgot his keys, and the same as the guy who breaks a lock to get into a burning building to save a child, etc. Obviously this is ridiculous, but even so, how could we possibly cover all of the motivations for breaking a lock?
How could we cover all of the motivations for hiding your identity? How could it ever be black and white if we can't?
If we could, then the entire justice system could then be automated.
