From chapter V of An Inquiry into the Nature and Causes of the Wealth of Nations by Adam Smith:
The real price of everything, what everything really costs to the man who wants to acquire it, is the toil and trouble of acquiring it. What everything is really worth to the man who has acquired it, and who wants to dispose of it or exchange it for something else, is the toil and trouble which it can save to himself, and which it can impose upon other people. What is bought with money or with goods is purchased by labour as much as what we acquire by the toil of our own body. That money or those goods indeed save us this toil.
In the first part of the quote, I understand that the true cost of acquiring something is the amount of effort and labor that it takes to acquire it.
However, the second part is confusing to me because when the author says "toil and trouble which it can save to himself".
Is the author arguing that exchanging a commodity for other things means being free of the cost of maintaining it and imposing that cost on the person who acquires it?
