The world today is not the same as during the times of the Great Tang.
After centuries of development, the maritime transport system has gradually matured. While not everyone can travel far, near-shore trade is within reach for everyone.
If maritime transport were completely opened, given the current speed of information management,
it would only lead to one result.
That is the excessive accumulation of wealth among the common people, leading to the rapid rise of local powerful forces, bringing Kyushu back on its old path.
This is by no means a good thing for a feudal dynasty.
The reason these people want Gu Lin to lift the restrictions is also quite simple.
They merely want to eliminate some of the costs associated with canal transport.
Besides that, they seek large-scale expansion.
It's worth mentioning that—
due to the presence of the Imperial Censorate and the Ryukyu Navy, the Gu Clan's regulation of maritime transport is very strict today.
