If you're worried about diaper wipes not decomposing, then get the ones that are designed to degrade in a septic tank. Look for the "safe for septic tanks" label on them. These are more biodegradable than the other types.
And as for scouts causing damage, our boys have always been trained to leave the campsite at least as clean as they found it. If you're going to rant about groups that damage campsites, why not rant against horse packers? One horse is going to leave more manure all over the ground than 10 boy scouts.
