TLDR: I want movecraft to be used more.

I wish there was more reasons to use movecraft. You really only see them get used on big town moves, a zep or 2 at a siege, or naval sieges, which most have truces about who controls them week to week.

I want more movement, I want large shipyards producing, and I don't want ships tied up for a year, only being moved if something is being built by it, I want trains shipping raw materials to a factory town, which sends its goods by zep and cargo ships to towns and nations all over the world.

Most train lines, ships, zepps, if not used for war are usually decorative. Even then most vehicles made for war are printed the day of, making dedicated shipyards useless, as all you need is 75 stone bricks and some chests.

I DO NOT HAVE AN ANSWER FOR WHAT WOULD MAKE THIS HAPPEN
Maybe have more region-specific resources,
specific types of towns that have different properties to them, like factory, shipyard, mining, etc.
Make town resources require an input, like food and other supplies for the imaginary citizens that are getting resources for you.

Those are just some suggestions, but I just want movecraft to be used more.
