Doesn't the concept of greed and selling apply to anyone who owns coins?
Indeed. The word greed implies some sort of moral superiority. Why work in a job that pays more than minimum wage if not for greed? Why speculate in altcoins if not for greed.
Debt used for anything other than emergencies: is that not greed too?
I accept your point though, it's a game-changer for a short while but is ultimately a war of attrition based on Mh/S.
On the point of the crash: I think you are underestimating the infrastructure fail (Gox lag whether DDoS or otherwise) that compounded the fall from $230 (or $266 if you don't believe in using the more useful daily close price).
