Doesn't pass the sniff test.

Even knowing how to make an item, was a big factor in what goods were available in the ancient world, see guilds. The Internet especially has changed that.

And until at least the age of sail, getting something from far away was a huge undertaking. Even today, supply chain logistics are hardly a solved problem.

Selling/marketing has always been part of trade, but it's hardly the whole story.

You can make a solid argument that in the last 100 years we became capable of producing more products than we need, causing the pinch point in our economy to move to competitively marketing and delivering them vs original building of them.

However hucksters have existed since the beginning of time to sell without producing. It’s why the Roman guilds and a bunch of other systems of verifying labor exist.
