How did he follow thru with his vision? Read his other comments to get better picture - he was angry at the system of Credit Cards, PayPals etc that charge outraged fees just to be able to use their network. He wanted to build network that performs exchange at zero fee. Instead, he ended up building and owning one of the most expensive crypto exchanges in the USA.
Sure props to him to pull it off, you don't get net worth of $20B by accident or pure luck... but in terms of his vision of the world more united where it is easier to send and receive money without paying outrages fees, he definitely failed on that promise.
