Agree!

Sketching 2D shapes is a very natural way to start thinking about shapes.

That's why there is a sketch + extrude.

Here are few examples - 42 seconds to a desk organizer

Or quick wavy vase.

The booleans and extrusion shapes are complements - both fitting different type of modeling.

Booleans are not only about shaping but also about composing individual parts to more complex assemblies.

So one can extrude few parts, then eg. combine them with a join.
