I agree that it is quite risky. States do not accept this currency not because the identity of the bitcoin Creator is hidden, but because they do not trust the technology. So I see no reason for the creator to reveal his secret.
The reason why satoshi did not reveal his identity is because he was afraid that he could be incarcerated for creating bitcoin, if I remember correctly close to the time when bitcoin was created there were several currencies that were centralized that were destroyed by the governments by using excuses and they put their creators behind bars, so if satoshi still alive I really think that he should never reveal his identity.
