Satoshi Nakamoto's anonymity have been Bitcoin's greatest strength and wether it was an intentional move or not,
I don't see this as the greatest strength to bitcoin, the nodes are the greatest strength from my own personal interpretation because once the nodes can't be attacked then the network remained perfect and secured, because everything over the blockchain technology follows a pattern of protocols which everything command or implementation must be in consensus of the written protocols for it to operate and work on, none can adjust, alter or attack it by any chance.
People do not know that Satoshi Nakamoto’s anonymity was primarily for his own protection and not necessarily to strengthen Bitcoin. Before disappearing, he ensured that Bitcoin was a decentralized system controlled by everyone, the community and not a single individual. If people truly understood that Satoshi has already fulfilled his role on Bitcoin, there would be less obsession over his identity. In fact, his reappearance could potentially have a negative impact on Bitcoin. Why worry about who created Bitcoin when it continues to thrive without him?
