It's not like those things weren't all getting done before. They just didn't generate commerce and didn't generate GDP. GDP goes up because of commodifying all those things. It's not clear if it's actually more efficient this way though.

That’s my point really, we just commercialized everything, and introduced a bunch of extra steps. Could argue it enabled us to scale and handle very large amounts of people residing together.
