This is kinda the conclusion that Steve Keen's Debunking Economics arrives at too, although amazingly enough, through a different path (avoiding breaking the monotonicity assumptions on supply and demand curves). Basically, any aggregate supply/demand model has a single consumer and a single product. Which makes them pretty much useless, and they just need to go.
