Bubbles are not by themselfs a problem. The property bubble in the US started collapsing in 2006 and by itself had no impact on employment or GDP.
Just as after the great depression when everybody believed overspeculation on the stock market had been the problem. Economist have studied this for 70 years and the practically universal conclusion was that montary policy errors was the real problem.
In Australia montary policy did not fail and they did not experiance a recession, the have not had one since the early 1990s. Whatever housing prices might do.
Simularly the stock market crash of 1987 (just as big as the one in 1929) did not even cause a blip in GDP.
Montary policy might have caused a little boom between 1926-1929 but if you really believe that the reslution of that boom required the US economy to contract by 30% then you are totally misguided. The problem was a contractionary montary policy.
The same goes for 2008, montary policy was the problem. Its the same story, everybody blames bubbles and speculators but economist have increasingly rejected this view.
Your story of 1926-1929 is basically the Rothbardian story, even his the majority of his studends and others influenced by him have since rejected this story. Its an intellectually dead idea that refuses to die because it perfect for the political left to demand control over all markets. Exactly what you advocate.
An independend central bank focus on macro economic stability should only have one job, stability of nominal demand.
Outside of that we can have political debates about how much banks and markets must be controlled.
