While it is true that gluing the pieces together does the same job of holding the pieces or fastening them together with a clamp, but what happens after you are done working with the piece and you need to detach the pieces? It would not be pleasant or easy to remove the glue and even if you manage to remove them, they might leave behind some sticky and stubborn residue which mars the beauty of the wood. Hence woodworkers appreciate clamps a lot and they understand their importance.
