Re: Craig W. only claims to be Satoshi, because he knows the real Satoshi is dead?
Just an idea. If Craig Wright is NOT Satoshi Nakamoto, he would definitely risk the real Satoshi come up with a proof, that Craig is not SN. Is it possible, that CW explicitly knows about the death of the person behind SN, so he can make his claims without backing them up with a proof? 
We don't know! We don't have any knowledge who is the real satoshi Nakamoto is and if he is still alive or not. We don't know why mr. Craig Wright is claiming that he is the real Satoshi Nakamoto, but the thing is what if he really knows who Satoshi Nakamoto is? And he already know that the real Satoshi Nakamoto doesn't have the plan on revealing himself so Mr. Craig Wright is claiming it in order to gain the popularity that he wants. What if that is the case?
