This is an interesting point of view, and it's shared by some strong players. I personally think the difference between a full-width search to 17 ply is going to be significantly stronger than a full-width search to 13 ply, always assuming the usual extensions on top of them. My feeling is that chess involves tactical subtleties that may not be apparent even to grandmasters, and the strategic and structural issues are only important if you survive the middle game. It must be emotionally very tiring to be that careful for that long. Against humans you can expect to get away with missing an occasional 16-ply trap.
