without the weight any transport methods in this game became utterly meaningless. its simply a part of the gameplay loop clearly. youre supposed to use the boats to transport large amounts of ore. this adds some risk. if the boat sinks during the trip to homebase the ore is lost.

the altanative is to bring the workstations to the ore location and smelt and craft at site. this wont help with iron tough as its needed for building aswell. same for chopper albeit far less than overused iron.

if you try to mod that away you may aswell cheat directly with dev commands and safe your precious time so you can play the game less.

aside iron metals are mostly used to make gear. if you could teleport it or it had no weight getting gear would be stupid easy. game isnt supposed to be stupid easy.
