Money is just a tool humans use to represent value. It is up to us to decide what is valuable. It's not about efficiency or inefficiency. You can't alone create everything. Food, water, power, maybe. But what about designing something great and complex? You could argue people would do this for free, but that's not right. A designer isn't an emoting artist seeking to express some particular vision. A designer solves humanity's problems. There's usually lots of things we want to express, but we don't have time to express them all. The way we select the problem to solve is by evaluating the economic potential of it. In other words, money makes people solve problems other people care about. It's the fitness function of technological evolution.
