. . . as laid out in http://dieoff.com/#economic_theory_for_scientists_and_engineers and I quote here verbatim:
What about energy and materials efficiency? Is the “market system” materials and energy efficient?
Our present method of distributing goods and services works something like this:
• Our government loans money to banks, so bankers can operate businesses (which require buildings, computers, furniture, lights, air conditioning, employees, commuting, etc.)
• The bankers then lend money to other businesses, like restaurants, real estate developers, etc. (which also require buildings, computers, commuters, advertising, accountants, etc.)
• So the employees of these restaurants, real estate developers, etc. can buy a car and drive to the store (with even more buildings, computers, commuters, etc.)
• Just to buy a loaf of bread!
The “market system” is the most-inefficient distribution system in the history of the planet!
Why not simply have government pay someone to pick up that loaf of bread at the bakery and deliver it to the consumer? This form of distribution would eliminate the banks, most of the other businesses, and all the stores. Most Americans would no longer need a car to commute to work or run to the store. However, some private businesses that provide critical services would still be operated, but at our government’s direction.
We could use the same energy efficient method of distribution for everything that Americans biologically “need.” Shoppers would order provisions online, in the same way that Amazon or Netflix works now, and then their orders would be delivered the next day. And a medical care caravan could regularly drive through neighborhoods, filling teeth, giving checkups, and so on.
