I agree, a brutalist fixation on efficiency isn't good. I just see rapid delivery and online shopping as things that are going to stick around, and those two things have completely broken most of the old brick and mortar models.

If it was just big box stores, we could have eventually pulled back and imposed a balance by limiting what range of goods and services could be offered by any one store, or come up with ways to prop up mom and pop. Amazon made those old models irrecoverably obsolete though. The question is going to be how to achieve a healthy market while keeping the benefits of vertical integration. Splitting the logistics division of Amazon away from the online store and content services might work.
