In 18th-century Britain, movement of either man or material was never easy. We may grumble about traffic gridlock and curse 4x4 drivers on the school run, but in those days they really had it tough. Cart-track roads turned into morasses in winter and river transport was governed by the weather - as well as being at the mercy of any miller who demanded water rights.
So any manufactured goods tended to be sold locally.
Canals were the way to travel for half a century until George Stephenson ushered in the era of railways - and suddenly the movement of goods became faster and more efficient. Then, when sail gave way to steam on the high seas, the transport revolution was complete.
