Because the toe clips will drag on the ground and, worse, interfere with cornering when you are using the SPD side of the pedals.
BTW, there are clip-in platforms that fasten to any SPD pedal and allow the use of plain shoes but detach for SPD use. Problem Solvers sells them but you will have to fit your own clips and straps. Winwood sells them both with and without the clips and straps.
