comment Definition of area
What is the higher-dimensional analog? That is, you could argue from this approach that the natural target of the area function is $K(Poly(2))$, and the fact that this turns out to be isomorphic to $\mathbb{R}$ is just a happy accident. So---for example---what is $K(Poly(3))$, the `natural target' of volume?

comment A tricky tractrix question about vertical tangents
Perhaps it would be easier to rotate $\pi\over2$ and search for $f'=0$.
