What makes capitalism distinctive is that, for capitalists, value is reckoned quite differently. While a capitalist might recognise the usefulness of things like chairs and pears, the goal of producing them isn’t to have a nice place to sit or a tasty afternoon snack, or even to sell them for other useful things. The goal is to produce and sell them for one purpose above all others: to make a profit. In this system, it is the ‘exchange-value’ of things that matters, not their use-value.
