The point is that its one of the fundamental principles of OSM 
that we collect facts not fiction. We collect stuff which
can be validated by anyone willing to visit a certain place.

If we start adding stuff with random private knowledge or fiction
which is not possible to validate on site we open a huge can of worms.

Most jurisdications (US may be different) explicitly state that
the public needs to be able to observe legal state. E.g. for
Germany, as long as there is no fence, signs or gates the public
can not observe that property is private and owners may not
assume so. So as long as there is no explicit observable fact
there is no way of liability or prosecution.

  Any sufficiently advanced technology is indistinguishable from magic.
