If I were Satoshi I'd prefer my identity to be a secret. When bitcoin was only a harmless little experiment Satoshi had no reasons to worry, but now when it became big and draws big money he should remain in hiding.
People are crazy, he'd need bodyguards and security systems to feel safe and even that wouldn't be able to protect him from the government.
Which begs the question, why did Satoshi's mindset present Bitcoin anonymously and remained such from the get-go if the experiment was benign? A marketing ploy or something quasi-sinister to have in place if or when the world's financial markets based on fiat begin their collapses as currently witnessed?
If Satoshi's a single person, perhaps a man, then in retrospect he's a pussy for not standing up facing whatever as so many men and women worldwide have in the face of persecution et al. while espousing their myriad respective causes in bettering humanity.
There are many possible reasons Satoshi choose to stay hidden, there are many inventors that have claimed to invent things like automobiles that run with water and stuff like that, and they claim they were visited by shady men trying to buy them out or threatening them, some claim they have been murders because of it, and we wonder why satoshi decided to remain hidden when his invention goes against the interest of banks and governments?
