It would be absurd to have Link at 1000$, Sergey would in that case be the wealthiest guy in the world.
Half of /biz/ would have a net-worth of more than 100 mio $.
I don't know how much of it can be directly translated into fiat or goods in general. Like if you had a 100K BTC you couldn't sell them at an exchange for the "current" price, and perhaps you never would be able to.
But this is strange times we live in, 20 years ago, all of the 10 largest companies (in terms of money) where companies that had existed for 50-100 years.. now we have companies like facebook and google, among the largest, and what is it they do? they are essentially internet based advertising agencies, which came into existence no more than 10 years ago.
