cnschulz and Warin, I think you are actually in agreement. Warin's OSM edits haven't yet been rendered on the map unless you zoom in to at least level 17. It sometimes takes a day or two to show fully.
If I'm understanding you correctly, cnschulz, the purple line that you posted does not have any private property issues. As Warin's route is east of your purple line, his route is just "walking through the national park".
On top of that, we do get that the designated track is closed, but that's a separate issue.
