This debate has been hashed out hundreds of times between other mappers and property owners. Please see https://wiki.openstreetmap.org/wiki/Why_we_won%27t_delete_roads_on_private_property

The result has invariably been that it is our database to do as we please with, and destroying this data is a form of computer vandalism. We are within our legal right to maintain this data, and it is illegal to destroy it. Trespassing issues are not the fault of our map data. We are collecting the same data that could be gleaned by legally flying over or photographing via satellite the concerned properties.

OpenStreetMap is used for many things beyond navigation. That you feel it should only be used for that purpose does not mean you can remove data serving other purposes.

Property owners affected by trespassing have effective methods of recourse that do not involve OpenStreetMap. I have reverted your changesets. Do not attempt any further deletions; they will be reported to the Data Working Group.
