The term commerce is from the 1530s, "social intercourse;" 1580s, "interchange of goods or property, trade," especially trade on a large scale by transportation between countries or different parts of the same country, from French commerce (14c.), from Latin commercium "trade, trafficking," from com "with, together" + merx (genitive mercis) "merchandise."
We engage in commerce daily. We trade goods, services, and ideas for units of value. Commerce does not need to be on a large scale. Having one's own business is not easy. Being the owner and being successful is rewarding. What is your commerce? What is your value?
