As do I! If anyone sees my car on a day to day basis, you would know exactly why. It is insanely dirty, mud up all the sides of the car. (Mudflaps have still stopped the majority of it, would be far worse without them) The car is parked on construction sites in the dirt and mud. So i consider them essential for my car. If it wasn't for that, i wouldn't have them and the car would be slammed to the floor. (even though the mudflaps already sit about 10-20mm off the ground...)
