It falls in line with other speculation like, exchanging closing during a sell to prevent a full sell-out (gox did it twice) and coinbase has a way of it's own.
But the problem with this one is volume.Yeah there are 200k unconfirmed transactions but
-how much is spam
-how much is close to dust level
-how much is just people moving around coins
To really make a dent in the markets you would need volume. And guys who can't afford 15$ per tx would not be able to do it.
Of course you could be one of those guys , transferring 2 million$ with a 3$ fee and waiting for two days already....

This process stops the bitcoin price to skyrocket,which is good for the market.
