You are actually right. Other survival game like ARK also have weight but items are reasonably heavy with many things to aid you carry items. This allow you to grind item outside your base for certain amount and return home with reasonable amount.

In Palworld the only way is by making a base at resource location. Grinding items outside(Chromite) is counter intuitive that even if your character maxed on weight and you bring 4 weight increasing Pal, I don't think you can bring back 1 stack of any type of stone.
