I'm not sure that provides an invalidation. There was unprecedented asset inflation during that period. Consumer inflation jumped at the same time the market realized that they were no longer making money hand over fist holding assets, no doubt in response to realizing that the only way to make money going forward was to produce something of value and charging accordingly.

You can print money endlessly, stuffing it into people's bank accounts limitlessly, and as long as they don't spend it you won't see inflation. But once they do start to spend it, the capacity to spend is magnified. Stocks, real estate, etc. provided essentially that bank account... until now.
