"but that's understandable" - Except it's the opposite of the USA. No right to camp on private land, but usually allowed on public land. There are a lot of different types of public land in the USA. Not just National Parks, but also National Forest ("forest", a misnomer, because that can include treeless mountain areas, deserts), BLM land. For most National Forst and BLM land, camp anywhere. For National Parks, some places you have to camp in designated campgrounds, but many huge areas where the rule is camp anywhere.

I'm saying, the management of public land in the USA is DIFFERENT. Even different than Canada.
