If you're confident that MtGox will eventually get their shit together and that bitcoin will have at least that value when you can, then it's a gamble worth taking.
It's not a gamble that I'm taking, but I understand the motivation of those who would.
Greed is a powerful motivator, but I'm with you. If MtGox hasn't gotten their shit together in the year since they started having problems, I don't see why they would now.
I would claim that all sorts of money-making schemes that involve bitcoins are more or less still gambling.
There is an exchange that trades real fake money and mtgox fake money.
