“When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it. You’ll know it’s there, so you’re going to use a beautiful piece of wood on the back. For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through.”
I think software as a whole suffers greatly from this "well, I got it barely done, technically fulfilling the requirements, so my work is over" attitude.

Using expensive wood or spending time doing things nobody will see will lower your throughout and raise your costs unnecessarily for the customer.
Even a master carpenter has finite time and money. Every morcel of time spent doing things nobody can see is time not spent doing other things with more visibility. The masters are still competing with other masters in a globally competitive market.
So Job’s fictional carpenter would get outcompeted by the hypothetical free market where carpenters of equal skill are producing more at lower cost.
Maybe someone should have explained to Jobs how to compete in the marketplace. Another approach is to try to understand why Jobs said those things given the obvious economic costs that you mention, and how it led to the most valuable company in the history of the world.
