"Why should the OSM community decisions override those of the communities who build these trails" - 

Because the map doesn't belong to you. OpenStreetMap is not a private registry for land managers or trail builders to curate what they think the public should or shouldn’t see. It’s a global, open, factual map of what exists on the ground. The job of OSM is not to enforce your access policies or preserve your status quo—it’s to reflect observable reality, transparently and accurately.

No one is denying the effort local communities put into trail building or land stewardship. But that doesn’t give you veto power over what gets mapped. If a trail is visible, verifiable, and walkable, then it belongs on the map—with appropriate tags like informal=yes, access=private, or hazard=yes. That’s how responsible mapping works.

Pretending something doesn’t exist by keeping it off the map doesn’t make it safer, doesn’t reduce usage, and doesn’t protect your community. It just makes users less informed. And that’s the real danger.

This is the last comment i'm gonna make in this thread as it is not the place for such a discussion. if you are serious about this then please start a discussion on https://community.openstreetmap.org/ and convince the community of your argument. 

Kind regards,
