You're referring to generalized historical patterns rather than what may or may not happen. The .com era pummeled pocketbooks of some of the most famous shorters. It happens almost everyday as well in a smaller scale...a company 'might' have a potential medical cure or prevention, a donut company becomes the latest fad...
Yes there is common sense investing that generally prevails in the current system, however that doesn't make the current system any less of a pyramid scheme.
If new money stopped coming into the markets, they would get crushed. Not because of an immediate change in fundamentals, but an immediate change in whether or not investors believed they could make money, which would cause selling.
