Unlike your subject line, this is no longer a "lisp style" question.

You just don't know lisp.

That's fine, but before asking "style" questions, you ought to learn
some lisp.  Get an introductory tutorial (there are good free ones
online!), try some examples.  After you learn a bit of lisp, and can
write simple programs, perhaps then you can come back with some style
questions.

Oh, and by the way: the functions your listed are not "the elementary
functions" (lisp has lots of functions, and there is no unique
elementary subset); nor can SETF be written in terms of the ones you
listed.

You see, wire telegraph is a kind of a very, very long cat. You pull his tail
in New York and his head is meowing in Los Angeles.  Do you understand this?
And radio operates exactly the same way: you send signals here, they receive
them there.  The only difference is that there is no cat.
