Market Dynamics
Asset price bubbles are always a problem - the issue over markets is their short term volatility and the short term pressures that drive valuations to extremes. As a simple example, and one close to the IT industry than property, was the dot com bubble. Those doing rational analysis on returns, potential values and so on were simply driven out of jobs an business by those speculating in the short term. The market dynamics drove short-term instability in prices. The same sort of dynamics happened in banking where the returns to individuals and organisations were short term in the form of bonuses, and the penalties of failures are visited on others (like the poor shareholder who is often an innocent in this). One of the most outrageous features of this whole game is the means by which the executives and high level dealers in banks and other institutions are able to manipulate the system to hide the truth from somebody just after a safe place for their pension investment.
An engineer designing a system will put in damping factors to control excessive amplitude variations. That means putting in modicums of negative feedback or time delay factors. The finance markets love of quick returns and instant gains drove this instability. It's a failure of market regulation that it allowed such practices and effectively penalised any longer term approach. It might be that futures markets could dampen these swings, but only if they are engineered correctly. The futures markets themselves have acted to increase these swings (see oil recently) as they still encourage short term speculation.
