Earlier quoted context omitted.
In practice it doesn't matter at all, just BLM (Bureau of Land Management) alone owns 387,500 sq mi of public land. For comparison, Scotland, is 30,090 sq mi in size . This is not counting local, state and national parks and forests. Why fix a problem that doesn't exist? Some of the largest parks are comparable in size to European countries. https://mapfight.xyz/map/yellowstone/ https://mapfight.xyz/map/death.valley/
Having to drive to a place to hike rather than just being able to go across the areas around you is annoying.
Unless European cities are smack in the middle of nature, I think they also have same issue.
