Short selling is what keeps the cheerleaders in check.

This. The market is supposed to be about circulating information (not necessarily making everyone well-off or saving San Francisco's Castro District or, or, or). And information that something might be overvalued is valuable information.

I'm not radically against regulation -- precisely because too often there are information asymmetries that markets (not only in capital but labor, consumer goods, etc.) can't penetrate -- but most people who think market economics should make things good (and be repressed otherwise) also think reality can be sustainably manipulated by good will, hope and faith in unicorns.
