Just think about slings and how effective even just throwing rocks can be compared to the force/pressure for water/wind to be equally damaging or how difficult it can be to actually set things on fire without heavy accelerant use.

This is more mystical elements where there can be philosophical properties attached beyond the physical.
That's why healing is under water.
That's why, at least at first, the explanation for metal bending was toph recognizing and manipulating mineral impurities(earth) in the metal instead of just realizing metal is a kind of earth.
Heck they even gave lighting to fire bending even though arguably that's equally or moreso an air thing.
