We also tend to congregate in high concentrations, since we have communication (and now social media!) to show all the best places. If everyone was dispersed camping on BLM land, somehow equally distributed regardless of distance from the road, it would probably be less of a problem, but when everyone wants to do ~the same extra special hikes and camp in the sameish spots, the concentration would get pretty high. Also, animal shit can be bad for the local environment. There's a lovely lake near us, and a nice big tree with a sign on it from the municipal parks department saying "Cormorants are using this tree to nest. Eventually, their droppings with kill the tree."
