If 7% of all bitcoins really are gone then the price rise would be more like 30% because the 7% were from the actively traded float, not from the several million hoarded and locked away in Arctic-cold storage.
You seem to be forgetting that there were also a lot of fiat afloat at mtgox that was meant for BTC. BTC will lose that fiat, and probably any new fiat that would of came from those who owned it.
It's fun to see how everyone are trying to downplay the gox situation and are trying to make this look good.
How much fiat was destined for btc that ended up getting gox paper btc. Now when funds are wired to an exchange to purchase btc they will be purchasing btc. Future fiat will have a greater impact as it's not traveling down a black hole.
there will also be a percentage of people who lost all of there stash but now fully buy into the bitcoin bull scenario. They must buy again
