I know that. Bitcoin's main risk is that it can make a person's fortune known, and accessible (or rather vulnerable.)
"You have 50,000 bitcoins.. transfer them to me now or alternatively do xxxx now .. or else." In fact some sort of time-lock or trusted partner would be a good busines idea, so that someone couldn't just come with a gun to your head. It can't become a world currency because it makes people too personally vulnerable... at least as it stands now, but it's a really good start.
What website will tell you how much BTC do I hold? If you can trace from some exchange or a merchant my identity linked to some bitcoins, you can equally do that with a gold dealer. Of course, you can see where bitcoins are moved, but that won't tell you much: they could be equally sold or simply relocated.
