> people have voted with their wallets and have said that Legos are worth greater than the sum of their parts
That's half a quote. The point you misquoted was very specific, regarding Legos being priced higher than their material costs works, because people value Legos for more than the plastic they're made with. That's not a tautology, that's a simple observation. This is without a doubt the worst conversation I've ever had about Legos.
