I don't disagree with any of this. I think there can certainly be value in learning outdoor skills and camping.
But in no way to I think it is the job of public schools to provide this, nor is it something taxpayers should be funding. My kid would benefit from touring Europe, Asia, Africa and Australia. It would most certainly be educational. She'd learn a great deal about history, art, architecture, languages, cultures, etc. But it's not the public school's mission to provide this for her. I don't see the camping trip as any different at all. MY job is to raise a well-rounded individual. Public schools shouldn't be expected to do everything.
I agree with your logic, but I think everyone draws the line in a different place. It could also be said that the public school shouldn't be expected to teach the kids how to play sports, do ceramics, play the clarinet or violin, construct a birdhouse, cook a meal, etc, yet these things are still taught in public schools, either through required courses or electives. I don't think any school district
needs to provide an outdoor ed program, but I think it's a great experience, and I'm glad to live in a district that does offer it.
2. Camping=Fort Wilderness with the family. Pooping in the woods and using a leaf for toilet paper is not something you have to experience to be a fully rounded person, imo.
This isn't "camping" though, it's "camp". There is a difference.

The kids are not sleeping in tents and pooping in the woods. They are in fully insulated and heated cabins/dorms with beds, clean running water, toilets, showers, and a dining hall with a kitchen where meals are cooked for them (except the one or two meals they cook outside as a learning experience).
The public school systems have no right to 'demand/require' that any parent send their child away for a week. Period.... End of discussion... No further comment. The school systems know NO limits...
I may have missed a comment, but I don't think anyone has said that these programs are mandatory. In our area, it's optional, but I don't know of a single child who didn't go. (Maybe I'll hear of some now that it's dd's turn to go.)
Are there no museums, zoos, or other educational venues within driving distances to make a day trip possible? Why aren't the parents encouraged to take a weekend a month and actually spend time with their child, taking them to a zoo, or spending time in the great outdoors vs. the school? My gosh, I saw the La Brea Tar Pits, Natural History Museum, Museum of Science and Industry, Art Museums...all kinds of well-rounded educational venues on the weekends when I was young, without the school supervising it. And all of those are still less expensive options than these camps seem to be. Have parents forgotten how to be parents, and encourage adventure and exploration in their children outside of school?
Reading some of these posts, it seems parent are expected to pay several hndres dollars for some of these camps. That same $$ could be spent by the parents for several weekend getaways to educational and family activities.
To answer your bolded question, because then they would all come to the DIS to complain of the nerve of the school district, telling them what to do with their kids on their own time!
Yea, we have zoos, museums, etc. Some parents take their kids there, some don't. The school still does field trips to those types of places, too, and charges the parents for the bus and any admission fee. Should we discontinue those field trips because it's the parents responsibility as well?
