You are so right. This is another side benefit brought to you by environmentalists. In the early 70’s they got laws passed prohibiting emptying gray water on the ground. They claimed little critters would eat soap filled food bits coming from the kitchen sink and get poisoned. Ok, we can all go with that. But was it enough? No no no. Then years later we wind up with EPA regs saying all private campgrounds must have sewer at every spot. Ever notice county state and national parks usually don’t have this “amenity”? Hahaha mr small business man, we’re exempt because it costs the government too much. Easy to see why the prices are high. Not just this regulation but all combined they add up. Gotta love the nanny state!
