> For comparison in the US dispersed camping
Good luck with dispersed camping in the US east of the Mississippi (or for that matter, in Texas). It is totally reliant on federal public land, which essentially exists only in the western states. Out east [0], or in Texas, you will find yourself in a situation much more similar to the one in France (or England, or Germany, or ...)
[0] and effectively, the east/west boundary is not even the Mississippi, but something like the 101st meridian. Dispersed camping in eastern Kansas is next-to-impossible.
