Huh?

You might have only 8 calls to `cons'. But your
code likely uses thousands of conses (aka cons
cells).
Except for atomic data types (strings, symbols
(including nil), vectors, arrays, numbers,
buffers, windows, frames, etc.), everything in
Lisp is built with cons cells.
Yeah, that's just a tautology.
(not (atom X)) == (consp X)
