I think a lot of these issues could be solved with a reworking of the inventory system, to restrict how much a player can carry (via a weight system, and or having items take up a different amount of slots). Like Zztong mentioned above, water is heavy, and having a restriction on how much you can carry especially early game can make things a lot more realistic and immersive. However, an inventory rework is far-off (if even in the realm of possibility) and doesn't necessarily pertain to the discussion at hand, so I digress.
