> In the end of the day you need a cooked dinner, a built house and everything else. So someone must build a house and exchange it for a cooked dinners.
You should read some history.This veiw is so naive and overconfident.
My views on this issue are shaped by history. Starting with crop production and plowing and ending with book printing, conveyor belts and microelectronics - creating tools that increase productivity has always led to increased availability of goods, and the only reason that has lead to decreased availability - is things that has hindered ability to create and exchange goods.
