The biggest reason I can speak of is that with NO diehredral, you lose some of the stability of the aircraft, and you lose some ground clearance in the event you have a crosswind to correct for. The standard practice is to crab into the crosswind until some point where you switch to a stabilized approach (I teach approx 200 feet or before) to bank into the wind and apply opposite rudder. This will cause a wing low landing, and if you have no diehedral you could have a very close wing tip. Also the diehredral adds to the stability, especially in planes that are low wings, due to the fact that it puts the fuselage lower relative to the main point of lift, adding a small pendelum effect (more pronounced in high wing planes). The diehedral has a leveling effect on the plane when upset by winds/updrafts etc...
