A huge percentage of economic activity has a strong correlation with real world utility. Food, clothing, housing, transportation, entertainment, childcare, medical care, banking services are all dependent on real utility being delivered in a short timeframe. If a top rated restaurant hired a new chef that was terrible and then failed it's health inspection and gave all of its customers food poisoning they would quickly lose perceived value.

I would agree that perceived value is more important than real value, but it is risky to place bets on there being a big difference between the two for a long time.
