Huh? A cart only requires 1 bar of bronze which you can easily transport and make in one quick trip to black forest.
I mean play the game the way you want but they made these limitations for a reason. They want you to craft and use ships to explore the world, and use them to transport the ore, rather than stay in one place and farm all the shit via portals. The first ship is pretty much same, 1 quick trip to black forest and youre sailing and transporting. Using portals to transport ore is like one of, if not the biggest cheats in this game IMO.
Infinite inventory weight? I mean come on. No movement speed degen wile wearing armor? those are huge cheats. My dude in full iron right now has something like -20% move speed, lol.
