Clean is a relative term. The reasoning is the same that you use to justify washing your hands with a mixture of soap and water, wipes allow you to use this same process to remove the fecal matter from your backside. If you missed while wiping with some single ply at a rest stop, would you clean your hand with only a dry towel? No, you would use soap and water. Even though you can't see large gobs of fecal matter it is still there. You try to make a strange point, the fact that some people don't use water to clean after is generally something that is reluctantly accepted, it is unusual to for someone argue that wiping without soap/water is just fine and to be preferred.
