That's painting all campgrounds with a very broad brush. We've been camping - in campgrounds and backpacking - for more than 30 years. Your choice may be to avoid campgrounds at all costs, but for us, they fit our needs and wishes, most of the time. There are some we would not return to. Some we go to are really pretty remote, one of our favorites is 45 minutes or so from the nearest town, no power, no cell service, etc. We don't boondock for many reasons, among them so many of the areas we like are being trampled by those that do. [in a USFS area of AZ we have not yet explored, I just saw a closure of at-large camping for the next two years, because it has been so over-used.] On many trips, we choose campgrounds by the places we want to explore. Mather Campground at South Rim of Grand Canyon is an example. Mix of close to pretty well separated sites, dry camping, in normal times often pretty busy. [Last October, we were among the 2 or 3 sites occupied in our section of a loop, around 17 sites.] Is it remote? No, but it is within walking distance, or a short drive, of the "big hole in the ground". Not going to miss that to drive miles to get there from a more remote spot.
