The problem is, in sections you will only be placing the objects you can see.
Not the ones hidden behind or are in front of the section or maybe not seen because the limits are cropping the section.
Or you may have 2 sections or elevations that basically show the same thing.
Anything objects placed in these will schedule twice (because you have to show them in each section) when in fact it should just be once.
Whereas modelling in plan (or 3D) you are placing all of the objects you want to be counted.
And as it modeled in 3D, it will appear correctly in your sections (if they are 3D objects - but they will still count correctly if only 2D).
This is why schedules only count what is placed in plan (and hence the 3D model).
And why there is only one plan 'view point' (yes you can save many plan 'views', but there is still only one plan 'view point' for each storey).
Whereas you can have as many elevation/section view points as you want and they can all show the same part of the model.
