I would postulate that protectionist "regulations" designed to hide protectionism in the form or "safety" or other regulations, creating barriers to entry in such a way that it prevents new, innovative ideas from coming to the market quickly and efficiently. The whole Technology surge of the last 20 years will be undone when "regulations" trying to prevent "bubbles" or other momentary inefficiencies will result in the abrupt end to the technology economy.
Yes, inefficiencies are part of a "free" economy, and often result in the busts that inevitably follow, as they are driven from the market. However, in no other kind of economy, can a person reach their full potential either, as restrictions in the form of regulations create the barriers to entry that effectively block them from doing so.
The end result is that in trying to prevent "harm" we actually do greater harm, that is masked in terms of stability. Stability is not necessarily a good thing, even while we desire it.
