I think if economic activity was reorganized around fundamental necessities (to a higher degree, I don't mean to a strict 100% extent) in aggregate this country would benefit by having investment and resources directed towards more productive ends. Certainly there would be short term friction associated with any type of restructuring like that, but better in the long run. Related to that he mentions the idea of income taxes replaced with sales taxes which I think is a great idea, incentivizing investment and savings over consumption.
