*Yes but.... some terms in the Fourier expansion of a square wave _DO_ exist. As I said in my previous post, there is almost always more than one way to derive something in physics or mathematics.

But those terms don't exist in the wavelet expansion of a square wave or many other decompositions of the square wave.  So they only "exist" for certain interpretations of "exist".
