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
No, that is not correct. While it's true that Bitcoin is decentralized and difficult to shut down completely, it's not because it can't be traced to a single person or organization. It's because the network is made up of many nodes around the world, and it would be nearly impossible to shut them all down. Satoshi doesn't have any special control over the network. Even if Satoshi was identified, there's nothing that anyone could do to change the Bitcoin network unless the community as a whole (or at least the majority of miners and mining pools) agrees to it. And the community is strong enough to resist any external pressures. Bitcoin was designed to be decentralized and resistant to control by any single entity, and it has proven to be just that.
