Can cross-border e-commerce completely replace traditional trade? Why

It is impossible. Large quantities of internationally traded goods must still circulate in the international market through normal foreign trade channels. Not to mention small commodities and electronics, which can be traded in cross-border trade. But steel, coal, ores, oil, timber, grain, etc., the volume of goods traded in these transactions are huge. For example, one shipment of soybeans imported from the United States, the need to use 100,000 tons of bulk carrier transportation, cross-border e-commerce perhaps a year may not be able to trade so many goods.
