If Gox gets shut down the price will almost certainly drop below to perhaps to the 10-30 range [...]
Bullshit.
Mt.Gox dying a slow, painful death at the hands of U.S. and Japanese regulators would be the best possible thing that could happen to Bitcoin at this point in time.
New exchanges and related services are popping up left and right.
All that would happen is a transfer of volume from Gox to elsewhere.
The government/TPTB are going to keep shutting down exchanges, and if you think this will drive bitcoin prices down, please sell all your coins now and get out because your market position is incongruent with your [incorrect] opinion regarding how government intervention/regulation affects prices.
The only reason e-Gold could be shut down was because it was centralized and thus had a single point of failure. When was the last time the government successfully stopped torrent downloads, or drove the price of drugs
down because of intervention, despite sketchy OTC availability situations? Gox is not a single point of failure, it's a poorly performing exchange that is only used because of its liquidity, which is a chicken/egg argument. Gox hurts bitcoin. Some people are stupid and need a "kick in the butt" to start using a different exchange, or they somehow believe that Gox will clean up their act after being given a million chances to do so. So regulators skewering Gox will give these folks the shove they need...
