That's not the point. It was that the market hypothesis of supply simply responding to demand doesn't actually hold.

People sell things based on their perception of future consumer sentiments, calculated margins, defensible moats, lots of things.

If someone wanted a compact sedan but the only thing for sale was SUVs, they aren't going to be like "I refuse! Bus pass for me" no. They will just bite the bullet and purchase the SUV.

Then the analysis will say "well people are buying the SUV! It looks very popular we should make more of them! I told you sedans were a bad idea!"

The supply and demand economics 101 ways of thinking are for fools and simpletons. It's why the iPhone wasn't a BlackBerry knockoff
