Why are the prices similar to campsites when some properties don't even have sanitary facilities?

A place in nature where you're alone or only in a limited number of people, far from crowded and noisy campsites, that's the greatest value. This is an exclusive experience and, on the contrary, we perceive the campsite as low-cost. Campsites may be cheaper because they try to get as many people on the their property as possible. But is it worth it? In addition, some of our properties have comparable amenities (but only for you).
