Commerce, trade and exchange make other people more valuable alive than dead, and mean that people try to anticipate what the other guy needs and wants. It engages the mechanisms of reciprocal altruism, as the evolutionary biologists call it, as opposed to raw dominance.
Interpretation
Commerce and trade enhance the value of individuals through mutual needs and altruism.
In this quote, Steven Pinker expresses the idea that commerce, trade, and exchange create a framework in which people are seen as more valuable in their living state rather than in death. This dynamic encourages individuals to consider the needs and wants of others, fostering a sense of reciprocal altruism, which contrasts with mere dominance and competition over resources.
In practice
This quote can be inspiring in a business seminar focusing on ethical commerce.
The foundation of individual rights is the assumption that people have wants and needs and are authorities on what those wants and needs are. If people's stated desires were just some kind of erasable inscription or reprogrammable brainwashing, any atrocity could be justified.
The linguistic clumsiness of tourists and students might be the price we pay for the linguistic genius we displayed as babies, just as the decrepitude of age in the price we pay for the vigor of youth.

We adults protect ourselves with laws, police, workplace regulations and social norms and there is no conceivable reason why children should be left more vulnerable, other that laziness or callousness in considering what life is like from their point of view.

Reason is non-negotiable. Try to argue against it, or to exclude it from some realm of knowledge, and you've already lost the argument, because you're using reason to make your case. ... We don't "believe" in reason.
The gentleman is calm and at ease. The gentleman is dignified but not proud; the small man is proud but not dignified.
It is perfectly possible to be enamoured of Paris while remaining totally indifferent or even hostile to the French.
Patriotism is "a very definite feeling of preference for one's own people or State above all other peoples and States, and a consequent wish to get for that people or State the greatest advantages and power that can be got - things which are obtainable only at the expense of the advantages and power of other peoples or States."
Ayn Rand's 'philosophy' is nearly perfect in its immorality, which makes the size of her audience all the more ominous and symptomatic as we enter a curious new phase in our society.... To justify and extol human greed and egotism is to my mind not only immoral, but evil.
The church is only the church when it exists for others. To make a start, it should give away all its property to those in need. The clergy must live solely on the free-will offerings of their congregations, or possibly engage in some secular calling. The church must share in the secular problems of ordinary human life, not dominating, but helping and serving. It must tell men of every calling what it means to live in Christ, to exist for others.
Man's life is like a drop of dew on a leaf.
