So I feel like I'm the only one in the world bothered by this, but I don't like how traders are so stationary. I feel like one of these days I'm gonna run into the perfect building spot, only to find a trader smack dab in the middle of it.
What if instead of pock marking the world with land claims, they could "move" around?
I think there should be a copper age block called the Trading post, that when next to a suitably sized flat area, would summon a trader and their cart about every month or so. You could also use the trading post to make a request for a specific trade(for a markup of course), or advertise an item you want to sell.
