I really don't get how something like a "money block" or insolvency should drive the price up, except there's a big demand from people, that have themselves dedicated to gox
by all means

All the insiders would transfer their btc to another wallet and request a fiat payout. As consequence we'd get a shortage in supply, but there should also be less demand on gox, because:
              - the price on other exchanges is cheaper
              - the discussion and opinions about that are free accessible to everybody
              - most people aren't that stupid. true story.

What do i not see?
