Satoshi Nakamoto is just a fictional character.
What do you mean by that? I mean just like in a movies, novel, comics or anime? That came up by just a mere imagination? We're talking aboutnreal thing here. It maybe just a pseudonym but what he did is real. It's not some kind of a fiction or imagination.
Only a dead person would be without desire for fame and fortune.
I don't know the real reason why he just vanished without a trace. It leads to assumptions that Satoshi Nakamoto is dead. But nope. There are some people out there today that don't desire money and fame. If there is one thing that can't resist by a genius (e.g.satoshi) it will be audience. That is one of the frailty of genius, it needs an audience.
What is so surprising if "Satoshi Nakamoto" is fictional? What's so hard to believe?
Think outside the box. You could find the truth out there.
Everyone (including people entering monastic life) desire money and fame.
In Buddhism, it was taught that souls on earth spend countless of eons going through countless cycles of life and death on earth while creating and settling karmic debt non-stop.
Only those who are truly liberated and ascended are without desire of money and fame.
"Satoshi Nakamoto" is not it.
