Why? The reason we're in this mess is because MtGox can't handle the volume of people who want in on bitcoin. There were 65,000 new accounts created on MtGox in all of March, but 20,000 *per day* in April. That's a 10 fold increase. And those people were willing to buy BTC when it was over $200. Why wouldn't they buy like crazy when BTC goes below $100?
