> If I want a pair of shoes I like, I go to the shop that sells them. > If I don't know those shoes exist, I will live happily, because I have no fabricated need to fulfill (and most probably if I'll know about them it's because a friend is wearing them) This reasoning is flawed because it ignores a common scenario: I want a pair of shoes, but none of the ones I find could fit me well enough. In other words, existing demand has not been met. Discovery has value.
