Satoshi. What did he found to create something like bitcoin?

[zorchy]

I have been reading a lot of documentaries in the internet (maybe a little bit of too much) 

So the question is why?
For someone to create something he must have a will to do it. He must have found something which is wrong with the currency that we are using now specially USD.

It is not written in his whitepaper.
So what could it be?

Suddenly after a successful programming and all the editing he have done which could be seen in this forum he vanished.
Is there a threat to his life?

Roth - when you google it one word or name suddenly pops out.

The Rothschild family is a wealthy Jewish family descending from Mayer Amschel Rothschild (1744–1812), a court factor to the German Landgraves of Hesse-Kassel in the Free City of Frankfurt, Holy Roman Empire, who established his banking business in the 1760s.

500 trillion worth. This goes on to their family from centuries ago until now.
Could they be a reason behind the sudden disappearance of Satoshi?
He is creating a currency where no one controls it. He became a threat. It could be a possibility.

Am I just full of imagination or it could be a possibility?
Please let me hear your opinions.
