alt Hacker NewsEvery socialist tries to make this distinction and falls to their own guillotine. You do realize that "substitute with" is merely a synonym for "exchange"?
The exchange of labor, to be sure, has existed nearly as long as civilization itself, perhaps longer, as all people cooperate by exchange through the division of labor right down to the family, and it is exchange whether the articles to be exchanged are money or physical things or even intangible, ephemeral things like love, pride, loyalty, or otherwise. Since human society is human cooperation by the division of labor, by your definition capitalism is nearly synonymous with human society itself. Fine by me.
This argument does not make any sense.
I have no problem with the concept of money. Commerce always the exchange of good and services, including on a symbolic level: as you point out, affection, money, etc. "Money" is not the distinguishing factor between commerce and capitalism.
At the risk of repeating myself: the distinction is how wealth is acquired. Capitalism allows one to acquire wealth merely by possessing capital, which in turn engenders unlimited capacity to acquire more capital. Capital is unique among all those systems for that reason.
