Yea, this is like the early railroads making steel cheaper via cheaper transport of bulk ore/coal, that made cheaper railroads, that then ship more products made of steel to larger markets opened by the extended rail networks, etc.
This happened with tin all the way back in the Bronze Age, where a lot of it was shipped as ingots from industrial-scale mines / smelters in Cornwall all the way to the Mediterranean empires to mix with copper to make Bronze.
A cog-based auto-catalytic wood industry is super interesting.
Also this stuff never happens by design. Some entrepreneur notices things and the costs, make a decision, suddenly more products exist, organic trading routes appear. There is no need for computers or grand design or hyper-managerial government. The market solves the problem
In the US context that's largely true, with the government providing useful regulations after the fact (allowing national corporations, railroad right-of-way law, etc.).
The exception being guys like JP Morgan who organized industry cartels that acted as private "central planners", part of which turned into the current Federal Reserve Bank.
But for countries like China and many others in Asia with strong state capacity, industrial policy was planned top-down for the "commanding heights" of industry like: roads, rail, shipping, airlines, telecom, steel, energy, etc., and that actually worked very well, faster than private markets alone, with the benefit of existing tech and models to follow.
We are talking about a sophisticated international trading system that happened 600 years ago. Clearly you don’t need anything like that to make it happen. Let alone Ancient Rome, Greece, Assyria, Sumer…
