If this is true does it mean that the identification of Satoshi as a person or organization will pose a treat to the existence of Bitcoin or otherwise
Bitcoin will still continue to exist, but it will not make any sense if Satoshi is known because its unknown is what bitcoin community like and proud about, that Satoshi does not interfere with anything and that as it is not known, it makes bitcoin to be decentralized and looks natural from the beginning when it was created.
Nothing can stop bitcoin from existing, you are right. It won't make any sense if the identity of Satoshi should be known, Satoshi is aware of this right from when bitcoin was formed. Satoshi identify not known is one of the success of bitcoin becoming well decentralized , people should always take this imagination from their mind because Satoshi will never identify himself to the public as the founder of bitcoin. Let's put our focus on bitcoin and forget about the identify of Satoshi, bitcoin is enough to think about.
