I don't know, man. If "A street urchin can't be a barbarian" and "A street urchin can be a barbarian, assuming a narratively coherent chain of transformative events" mean pretty much the same thing to you, there's going to be communication problems.
I'm not sure what you mean by that. I've been saying that they are not the same thing this entire portion of the thread. A street urchin can't be a barbarian. Exceptions exist to virtually every rule, but only under very specific sets of circumstances. If a player wants to be an exception, they will need to explain HOW they are an exception in a way that makes sense.
People are obviously assuming a rationale between the transformation from state A (background) and state B (1st level character), because there's a ton of narrative space in between.
No such rationale is given and I'm not going to assume that they mean anything other than a typical street urchin can be a barbarian if he's angry, if that's what they are saying. The only thing some of them have given as their rationale is aging.
