I agree with this. People are concerned with wealth distribution in the physical world, while in the bitcoin world one man owns nearly 10% of all money. The fact that this man is its creator is even more dubious.
This is the equivalent of one American, someone like the head of the federal reserve owning 1.05 trillion US dollars. Even if one day we'll have 21 million Bitcoins out there, that's still around 5% of all wealth being owned by one man, the currencies creator. Sounds crazy to me.
